Years of Cut Calls and Poor Reception

I have lived at my current address since 2017 and have never enjoyed good reception from Vodacom. Over the years I have tried to have the issue addressed, but with no luck. Today I called to cancel my contract so that I can move on to another service provider who can give me better service, and unfortunately the phone cut as I was talking to the consultant. I tried calling again, and again the connection was bad and inaudible. So, since I am not having any success telephonically, and there is seemingly no way to cancel my contract via the app, I am hoping that someone will see this and assist me with cancellation. I am no longer interested in any improvements here. If any are made it will be for the benefit of other Vodacom users. Not me. I am moving on.
