Requested cancellation on vitality membership 4 months to cancel vitality membership and it still hasn’t been done!!!!

I requested a cancellation on my vitality at the beginning of May and was told it’ll take 30 days to be canceled. The account was debited in May, June which I reversed and a double debit in July. Each of these months I’ve called in to cancel and get a confirmation email to say it’s been cancelled but at the end of each month they still continue to debit. I have called multiple times and all they ever do is move me from one person to the next, none of these people are helpful or seem to know what’s going on!!!

Just cancel it.. how hard can it be to cancel a single vitality membership.
