Cancellation of contract

Account number ***. I have been trying to cancel this month to month data bundle for the last three months. Icalled in on either the 15th or 16th December and spoke to a guy by the name of Wonga in the retentions department. He confirmed that it was a month to month contract and if in arrears he would not be able to cancel. He advised that the contract will ne cancelled. I never received any confirmation of cancellation. I emailed the collections department and received a call on the 1st January 2022 I received a call and the same story repeated itself. I told the lsdy of the above and the more i repeated that I had repeated asked this to be cancelled she eventually said the contract will be cancelled and that I will receive an sms to my cell number confirming tjis. To date I have received nothing. I now received a statement for arrears plus another fee of R70 x 2. I am paying extra bank charges for returned debit orders and now an extra fee payable to cellc. I am very dissatified with cellc and hope they can sorr this out a.s.a.p. i need this contract cancelled. When I first asked for camcellation i was not on arrears. Cellc your urgent attention to this matter is required.
