Before you cancel Complete Nutrition, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
