Block your card fast after a scam

Block your card first

If a scam used your card details, whether for one payment or an ongoing subscription, block the card before anything else. This stops it being charged again while you sort out the rest.

Call your bank’s card hotline or use the block feature inside the banking app if one exists. Both work, but the phone line lets you explain the situation at the same time.

Do this even if you are not certain the card details were fully compromised. A blocked card is easy to replace, but a card used repeatedly is not.

Why blocking stops more than one payment

A single card scam rarely means a single charge. The same details can be charged again, sold on, or used for other purchases once they are in the wrong hands.

Blocking removes that card from use entirely, closing off every future attempt at once. This matters even more if the scam involved a subscription or a recurring charge that would otherwise continue billing.

A new card number usually arrives within days, so blocking costs you inconvenience, not money.

Start the dispute once the card is safe

With the card blocked, raise a dispute for the charge itself in the same call if possible. Tell the bank the transaction was unauthorised or tied to a scam, and give the date and amount.

Read how a card chargeback works to understand what qualifies and roughly how long the process takes. A dispute is separate from the block, so both steps are needed.

Ask for a reference number for the dispute, since you will need it if you have to follow up later.

What to have ready when you call

Have the transaction details ready: the amount, the date, and the merchant or platform name shown on your statement. If you have screenshots of the offer or your communication with the seller, keep them aside.

A clear, short account of what happened helps the call move faster than a detailed retelling of the whole scam. You can add more detail in writing afterward if the bank asks for it.

What to do next

Once the card is blocked and the dispute is raised, file a police report as well, since it supports the dispute and any later steps. Keep every reference number in one place.
