Find the cancellation route the operator keeps off its front page, check your notice period and whether you are still inside a binding time, then cancel in writing and keep the confirmation. Expect one more invoice before it stops.
Or have it done for you: the app finds the route, checks the dates, and walks the cancellation through on your own computer, and then does the rest of them too.
Every operator makes this harder than it needs to be, because the page you are looking for is designed to keep you. Here is how to do it yourself, and what to watch for.
The step-by-step method is not on this page yet. It is being written from cancellations we have actually run, operator by operator, because the operators' own help pages are what everyone else already has, and they are often wrong. Until it is here, the short version at the top of the page is the whole of what we will put our name to.
When it is here, this is what it will cover, for each of the operators people search for most:
At Your Service finds the cancellation route for your operator, checks your notice period and any binding time you are still inside, and walks it through for you. If it needs you to sign in, it asks. Before anything is sent, you see exactly what it is about to do. It runs on your own computer and nothing about your accounts leaves it, and it does the rest of them too, not just this one.
You decide what it is worth after you have seen what it saved. There is no monthly price. There is a number, and a slider you set from it.
It starts by having a look at your spending, and the subscription you came for is the first thing it asks about.
