Cell C Fibre failed to close my acount

I have been a client of cell c fibre for years I always paid on time and have never missed a payment.When it was time to close my account, I was told to send and email instructing cell c fibre support team to close the account. I did just that and I even received a ticket number for my request. Two months later the account is still not closed and the debit order is still not cancelled. Even though I sent an email telling the cell c fibre support team that I am moving out of the property,even though I have called and followed up with email but still I am required to pay. I am now being bul**** to pay for a fibre connection that I physical don't even have access to.
