What to do if…
you get a “chargeback” notification and you think someone is trying to reverse a legitimate payment

Short answer

Treat it like a deadline-driven admin emergency: confirm the notice is real in your payment provider/acquirer portal, note the “respond by” date and dispute reason, then either accept it quickly or submit a short, reason-matched evidence pack.

Do not do these things

  • Don’t ignore it — missing the response deadline can lose the case automatically.
  • Don’t click links in the notification email if you’re not 100% sure it’s genuine; log in via your usual bookmark/app instead.
  • Don’t contact the customer angrily, threaten them, or post about them publicly.
  • Don’t upload a huge, messy bundle of screenshots; irrelevant or unreadable evidence is often treated as no evidence.
  • Don’t issue a refund “just in case” and also submit a dispute unless your provider says that’s appropriate for the stage you’re in.

What to do now

  1. Open the case inside your provider/acquirer portal (not via email links) and capture the key details:
    • dispute reason/category (and any reason code shown),
    • deadline to respond,
    • amount and any fee,
    • the transaction ID and order reference,
    • the current stage (e.g., initial dispute/chargeback).
  2. Sanity-check that the notification is real (2 minutes):
    • Compare it with your normal provider emails and then confirm the same case appears when you log in normally.
    • If anything looks off, treat it as possible phishing and contact your provider using a known, official route (saved number/help centre inside the dashboard).
  3. Choose your path: accept vs challenge (before you gather lots of documents).
    • Accept if you can’t directly disprove the stated reason (e.g., no delivery proof for “not received”), or the time/cost outweighs the amount.
    • Challenge only if you can clearly answer the reason with specific evidence.
  4. Pull only evidence that matches the stated reason (keep it tight and legible). Examples:
    • “Unauthorised / fraud”: proof the cardholder participated or benefited (account history, login/IP/device data you already lawfully hold, prior successful transactions, proof of digital access/usage, delivery to a consistent address).
    • “Not received”: carrier tracking, delivery confirmation, dispatch date, the address used, any delivery communications.
    • “Not as described / cancelled / refund expected”: the product/service description shown at purchase, what was actually delivered, your cancellation/returns terms as presented at checkout, your messages with the customer, and any refund record/timestamp if relevant.
    • Always include: order/invoice, date/time, amount, item/service details, and customer communications.
  5. Write a short rebuttal summary (half a page is plenty):
    • 1 sentence: you’re disputing the chargeback for the stated reason,
    • 3–6 bullets that link each key attachment to the reason,
    • a simple timeline (purchase → fulfilment/access → any customer contact → today).
  6. Submit through the provider/acquirer portal before the deadline and save proof.
    • Save the confirmation, and keep a copy of exactly what you uploaded.
  7. Do a quick “is this part of a wider issue?” check (10 minutes):
    • Look for other disputes tied to the same email, address, device, or product.
    • In your payment dashboard, review recent admin/staff logins and any changes to payout/bank details (chargeback emails are a common phishing hook).
  8. If you suspect fraud beyond a normal dispute (optional):
    • England, Wales, Northern Ireland: report cyber crime/fraud to Report Fraud (online, or by phone on 0300 123 2040, Monday to Friday 8am–8pm).
    • Scotland: report to Police Scotland (typically via 101 for non-emergencies).

What can wait

  • You do not need to decide today whether to take legal action, use debt collection, or overhaul your entire checkout process.
  • You do not need a long back-and-forth with the customer right now — the provider/acquirer deadline comes first.
  • You do not need “perfect” evidence — you need relevant evidence that directly answers the dispute reason.

Important reassurance

A chargeback notice feels personal, but it’s often just the card issuer’s dispute process. Many legitimate businesses get them. The best first response is calm, organised, and deadline-focused.

Scope note

This is first-steps-only guidance to stabilise the situation and prevent irreversible mistakes. If disputes are frequent or high-value, you may need specialist help from your acquirer/payment provider or a qualified adviser.

Important note

This is general information, not legal or financial advice. Chargeback rules and evidence requirements vary by card scheme, provider, and dispute reason. Always follow the instructions and deadlines shown in your actual case.
