Quick answer
Open the last three statements and flag every line that repeats at the same amount. Then cancel on the merchant's own website or app, which is the only cancellation that actually ends the contract, and keep the confirmation email. If the charge keeps coming, ask your card issuer to block future payments from that merchant and dispute the transaction.
A card statement is where subscriptions hide best. They arrive diluted among ordinary purchases, under names that look nothing like the service, in amounts small enough not to draw attention. Added up, they become the largest invisible line in a lot of household budgets. This guide shows how to identify every recurring charge, work out which company it belongs to, cancel it for good and dispute it when there is no other way out.
Almost always the explanation is one of these four, in order of frequency:
Open the last three statements, not just the current one. Annual and quarterly subscriptions only surface when you look at a wider window. Go line by line and flag everything that repeats at the same amount around the same point in the month. Write it into a simple list with four columns: the name as it appears on the statement, the amount, the billing day, and whether you recognise it.
Some issuers and neobanks already do part of this work and group recurring purchases onto a screen of their own. Worth checking whether yours does, but do not rely on it alone: those lists only cover that one card and tend to miss charges whose amount changes.
Before you involve the bank, try to identify the source. Three routes solve most cases:
This is the step that actually ends the billing. Sign in to your account on the company's website or app and look for "Subscription", "Plan" or "Account". The cancel option is almost always there, even when it is buried two or three clicks deep.
Three things that save you from doing this twice:
If the subscription was bought inside an iPhone app, cancellation happens in Settings > your name > Subscriptions, as described on Apple's official support page. Deleting the app cancels nothing, and it is the most common mistake of all.
Prism brings every subscription into one place, works out your real monthly spend and warns you a day before each charge. Free, private, no account.

Most banking apps offer, on the transaction screen, an option to block future payments from that merchant. In the UK you have a specific right to cancel a recurring card payment, a continuous payment authority, directly with your bank, and the bank must stop it when you ask, as Citizens Advice explains.
Just understand what it means: blocking stops the payment, it does not end the contract. The company can still treat you as unpaid, add fees and send the balance to collections, which shows up on your credit file. That is why blocking is step four and never step one.
A dispute, or chargeback, is the process where you ask your card issuer to reverse a payment you should not have made. It is the right path for an unauthorised charge, a duplicated charge, or a charge that keeps coming after a cancellation you can prove.
If it is fraud, also ask for the card to be blocked and a new number issued straight away. It is the only way to stop further attempts.
Sometimes, and less often than people assume. Card networks run automatic account updater services, used by large subscription merchants, that pass your new number along without you doing anything. In other words: you replace the card and the charge reappears next month. Getting a new number works well against fraud and against small merchants, but it is not a substitute for a formal cancellation.
The pattern that creates the problem is always the same: the billing is automatic and the review is not. To flip that, three habits are enough:
Keeping that in a spreadsheet works at first and dies by the third review. A dedicated app like Prism, the subscription manager for iPhone, does the maths and the alerting for you, and keeps the data on your device only.
Cancel with the merchant first, keeping the confirmation email. Only after that, if the charge keeps coming, ask your issuer to block future payments. Blocking without cancelling leaves the contract open and can turn into a debt.
If the charge was unauthorised or kept coming after a cancellation you can prove, yes: dispute it with your issuer and attach the evidence. If you simply forgot to cancel a service that was available to you, a refund depends on the merchant's policy and is often refused.
No. The contract with each service still exists and the merchant can bill you another way or send the balance to collections. Card network account updater services can also pass your new card number to the merchant automatically.
It varies by issuer and card network, and usually takes from a few days to several weeks, because the merchant is given time to respond. Track it in the app and keep every reference number.
