Keep charging after cancellation

My partner cancelled his account and then they keep charging for it. We’ve emailed support several times and even though on the website they say they will respond within 24 hours, it’s been one month since the first email. They don’t send a cancellation confirmation or anything. We’ve tried logging into his account but it says there’s no account with his email. But when we try and sign up again it says welcome back, login in with your password.

Marvelous results from Réunion Island

I like this kind of follow up: complete and evolutive. The data base for the nutrition part is insane: you can find all food in it! And at the end of each training, I find funny to know how many moose or gorillas I pulled or pushed up 😁
