Did you get confirmation email of said cancellation? If not the process wasn't completed.
How many memberships do you have? As cancelling one doesn't automatically cancel them all.
Yea I did and I cancelled all subscriptions
If you received cancellation emails for ALL memberships, then you need to speak with staff via live chat. As they won't be on here.
