Refund my subscriptions

I am extremely dissatisfied with the service i have been receiving from Telkom. I have logged numerous queries with your office to no avail. I had an issue with my adsl line,that i had cancelled October 2021.Your company kept debiting me ever since. I recently called and cancelled again,and was promised a refund.I heard nothing and called again,and was told that another dispute was lodged.I know i wont hear anything from that ,hence im resorting to HelloPeter.My landline number ***,my dispute reference is ***7,i was also advised that i need to provide the initial reference number for when my adsl line was down.I do not have it,surely your system should have record against my profile of all queries i have logged with your office.The call centre had mentioned that they have no record of that.
