Please help

I notified Telkom in March 2020 that I would be moving house and need my landline to be moved. I also advised them that I needed to cancel ADSL because I had engaged Webafrica to provide my internet service. To date Telkom continues to charge me for the ADSL. I have visited their offices countless times since March 2020 but there is no joy. When I call them, their consultants, on many occasions, cut the call. Frustrated member.
