Before you cancel Factorio, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
