At my wits end. Just want my account back to normal

In May 2019 I called telkom to relocate my adsl line as we had purchased a property and we were moving in June. I was told there were no ports available but that I could install a line at my new property and wait for a port to be available. We had no working adsl at that stage for a few months due to cable theft and we were in credit. In June a technician came out and installed a line after which we had internet for a few weeks not realizing it was only trial internet and only a voice line had been installed not one set up for adsl. Many calls to telkom later I was given the run around for months a call agent added the wrong services to my account. 2 tin numbers 2 broad band numbers and capped services which I did not apply for. For months we were unable to have internet due to a tin not being generated on the system, then there as an error etc. Finally in October a technician came out and our adsl was working but since August of last year we have been billed for all these incorrect services and now in February the second broad band number is still active on my account and I am being billed for it. When I call telkom I am told they cannot delete the incorrect service and a dispute is logged but I am still being charged!! I feel like canceling my contract but I know that will be futile as cancelations are not processed correctly and I will still be billed. I can't even cancel my debit order with them :( if someone from telkom can please help me with this I would be so grateful
