Telkom refuses to cancel my contract.

Telkom is ripping me off. I took a data and route contract for 12 month. I took out a contract on the 1 March 2019 and till today they have been debited. I went to the telkom office and requested cancelation 3 month before the time. This was done on the 1 December 2019 when I went to the telkom office. A telkom consulted contacted me and advised that my cancelation will canceled in January 2020. My account was debited in Jan and Feb and March 2020. I then contacted telkom call Centre they said I was placed on a month to month contract with out my consent. I have been calling to cancel since March. I even went as far as a reversal and received calls from the debit collectors. Since then I have been have trying to cancel on the website and the call Centre as the telkom office advised me to cancel at the call Centre until this when the telkom office advised that it will be canceled in November. I received an sms from the retentions department saying that they can only cancel in January and that my account is in arrears but they placed me on a month to month basis with out my consent. I would my contract to be canceled and refunded for 6 months as I have not used their service or their sim card, telkom went as far as charging me for a device and data after the term of contract. Worst service ever, biggest *******.
