Pathetic experience with cancellations department

My contract ended the end of January 2021. I have tried to cancel the contract since the end of January. The cancellations department has been unable to assist me with this matter. The cancellation was NEVER processed and each time I call to follow up nobody can tell me why the cancellation has not been completed. They have STILL been debiting my account despite my request to cancel. This has been the worst customer service experience. Their customer service is pathetic and it seems like nobody knows what’s going on but and constantly try to sell me deals. They are more than happy to take your money but cannot follow through with a simple request.
