Horrible service from Telkom

My contract with Telkom is being a problem, and I want to make a cancellation on one of my contracts. I tried phoning Telkom a few times on different days and was cut off every time, then I had them phone me and got cut off again. So I went into a Telkom store, but they could not assist and put me on the phone with Telkom. I got cut off twice more. The man told me this was normal. When I asked for an email address to contact them I was told that that is only for Telkom Business.
