Dispute Resolution Speed: TribeCar, Endowus, MariBank, GXS & Trust Bank Ranked (2026)

Endowus commits in writing to a 20-business-day complaint resolution target under MAS regulations, MariBank and GXS both commit to 21 business/working days (up to 45 for complex cases), and Trust Bank has not published its own dispute SLA at all — so if speed and certainty matter to you, Endowus and the two digital banks give you something concrete to hold them to, while Trust Bank does not.

Why dispute resolution speed matters

Most comparisons of digital banks and investment platforms in Singapore stop at interest rates, fees, and sign-up bonuses. They rarely ask the question that matters most the one time something actually goes wrong: an unrecognised transaction, a double charge, or a transfer that never arrived. How long will the platform take to investigate, and what happens if you’re not satisfied with the outcome?

This matters more for digital-only platforms than for traditional banks. There’s no branch to walk into, no relationship manager to escalate to in person — the written SLA (service level agreement) in the help centre is often the only commitment you have. We pulled that commitment, word for word, from five platforms covered on TribeCar, Endowus, MariBank, GXS, and Trust Bank, and ranked them by what they actually promise — not by their reputation.

How we ranked these five platforms

Each platform’s own help centre was checked for: (1) an acknowledgement commitment — how fast they confirm your report was received, (2) an investigation window — the maximum number of days they commit to before giving you an outcome, and (3) an escalation path — what you can do if you disagree with that outcome. A platform that publishes all three, with specific day counts, ranks above one that only offers vague reassurance.

Endowus: fastest published target, but it’s a complaint, not a transaction dispute

Endowus doesn’t process card payments or bank transfers in the way a digital bank does, so its process is framed as a formal complaint under MAS’s Financial Advisers (Complaints Handling and Resolution) Regulations 2021. In practice: email complaints@endowus.com with your full name, contact details, a description of the issue, and any staff names involved. Endowus commits to acknowledging receipt within 2 business days and aims to resolve the complaint within 20 business days, with a written final response. If it needs longer, it must tell you why and give you an updated timeframe.

This is the fastest published number among the five, and it’s backed by a named regulation rather than a goodwill promise — a meaningful difference if you ever need to point to something in writing.

MariBank: 21-business-day window with a clear new-evidence reopen clause

For an unauthorised transaction, MariBank asks you to lock your card immediately in-app or call its 24-hour hotline (+65 6995 8688), and to file a police report if fraud is suspected. After you submit the report, MariBank acknowledges it by email and commits to an investigation outcome within 21 business days, extending to up to 45 business days for complex cases. If you disagree with the outcome, MariBank’s help centre states its initial finding is “generally final” unless you supply genuinely new evidence not considered the first time — and if you’re still unsatisfied after that, you can escalate to the Financial Industry Disputes Resolution Centre (FIDReC) at fidrec.com.sg.

GXS: same 21-day window for fraud, but a much slower track for card disputes

GXS splits its process into two tracks that are easy to confuse. For an unauthorised transaction (you’re certain you didn’t make it), GXS commits to the same structure as MariBank: up to 21 working days once it has everything it needs (including a police report if requested), extending to 45 working days for complex cases. But for a merchant/card dispute — wrong amount charged, goods not received, duplicate charge — GXS’s own help centre says investigation “may take about 12 weeks” (roughly 84 days) assuming documents are submitted promptly, and it only accepts disputes filed within 60 days of the original transaction. If GXS finds you’re not liable, it credits your GXS Savings Account or waives the corresponding FlexiLoan amount. Unhappy with the outcome either way, the same FIDReC escalation route applies.

Trust Bank: no published SLA we could find

This is the one genuine gap in this comparison. Searching Trust Bank’s own site and help centre, we could not locate a published number of days for dispute acknowledgement, investigation, or resolution — unlike Endowus, MariBank, and GXS, which all state specific day counts in writing. General Singapore card-dispute guidance (SingSaver, HSBC) suggests the market-wide norm for banks and digital banks is roughly 30 to 90 days for a full chargeback resolution, with a typical 120-day filing window from the transaction date and a recommendation to submit within 14 days of the statement showing the charge. Trust Bank customers should ask support directly for its written timeline rather than relying on these general figures, which is exactly why Trust Bank ranks last here — not because its process is necessarily slower, but because it hasn’t told you how long to expect.

TribeCar: a different kind of dispute entirely

TribeCar isn’t a bank or investment platform, so it doesn’t have an unauthorised-transaction or chargeback process in the same sense. A “dispute” on TribeCar usually means a damage or excess claim after a rental — a separate car-sharing insurance process governed by your rental agreement, not a MAS-regulated financial dispute with FIDReC recourse. We’ve included TribeCar in this 5-platform combo for consistency with our usual TribeCar combo series, but it is flagged out of the direct comparison below rather than forced into an apples-to-oranges ranking.

What to do the moment you spot a problem

Across all four financial platforms, the first hour matters more than the fine print on resolution days:

• Lock or freeze the account/card immediately in-app — MariBank and GXS both let you do this yourself before calling support.
• Screenshot the transaction before you report it, including the merchant name, date, and amount — overseas transactions often post under a different date or merchant name due to time zones and payment processors.
• File a police report if you suspect fraud or a scam — MariBank and GXS both say this materially speeds up their own investigation, and FIDReC may ask for it too.
• Get the acknowledgement in writing (email or in-app confirmation) with a reference number — this is your evidence of when the clock started.
• Respond fast to any follow-up requests — every platform’s stated timeline assumes you provide requested documents promptly; delays on your end reset or extend the clock.
• Know your escalation route in advance — for Endowus, MariBank, and GXS, that’s FIDReC (fidrec.com.sg, +65 6327 8878) if you’re unsatisfied with the final outcome.

A note on scope before the FAQ

This comparison covers each platform’s own published complaint and dispute-handling process as at October 2026. It does not cover insurance claims, CPF-related disputes, or TribeCar’s rental damage process, which sit outside MAS’s financial dispute framework. If you’re deciding where to park cash or invest in the first place, our platform comparison series and retirement planning tools cover rates and fees in depth.
