A Cancellation That Actually Stops the Charge
Cancel early, keep the dated confirmation, know your statement descriptor — the three things that decide whether you get billed again.
What it is for
People cancel, get no dated confirmation, and are billed again — at which point it is their word against the merchant's. This sets the timing, defines what counts as proof, and gives the escalation order if a charge lands anyway, including the statement descriptor you will need. Use it the day you cancel, and the day you start a free trial.
The skill
"I cancelled" is worth nothing next month. A dated confirmation is worth everything. Work backwards from that. Timing: - Cancel several days before the renewal date, not on it. Subscriptions bill in advance and time zones are not on your side. - The day you start a free trial, put the end date in your calendar two days early. Every trial is designed around you forgetting. What actually counts as cancelled: - A confirmation email or screen naming the service, the date access ends, and ideally a reference. Screenshot it. - The account page afterwards, showing no active plan. Screenshot that too. - A support agent saying "that's done for you" in a chat window is not proof. Ask for it in writing before you close the window. Write down the merchant descriptor exactly as it appears on your bank statement. It is rarely the brand name, and it is the string you will need if this becomes a dispute. If you are billed anyway: 1. One written message to the merchant, attaching the confirmation, asking for the refund by a specific date. 2. If that date passes, dispute it with your bank or card issuer and attach the same evidence. The chronology is what wins it. Do not rely on blocking the card or letting it expire. Recurring charges can follow a replaced card, and an unpaid amount can still be pursued as a debt. Do not cancel mid-cycle expecting a refund for the unused part. Most services do not give one and you usually keep access until the period ends — so cancel now and keep using it. None of this is legal advice, and consumer rules differ by country. Where a contract has a notice period or an early-termination fee, read that clause before you cancel anything.
How to install it
1. Open the tool and start a new conversation, project or template. 2. Paste the text below wherever the tool keeps standing instructions — usually called system prompt, instructions, or persona. 3. Save it so it applies to every run rather than a single message.
