Before you cancel Hachette Partworks, 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
