Big on deals, poor in service!

I have sent the requested documentation to Telkom to cancel my contract on 13 November and was told that it takes 28 days. I am STILL waiting for my request to be actioned. I have called the call center 4 times in the last week to query this, and they give me the same pathetic answer. I even spoke to a team leader ********** and still waiting for the feedback he promised 2 days ago. But my ever end was speaking to Zama at the Durban call center now, I explained that I am not interested in hearing the process again and i want feedback on the cancellation, she tells me that seeing that I dont want to hear the process, she is placing me on hold then. After a 10 minute wait holding, she drops the call! I am still in total shock! Is this how telkom trains their staff?? Is this the kind of service we receive? This is the 2nd problem i have with telkom in the last 6 months! After switching my whole family to telkom, I am starting to think it was a big mistake... Big on deals, poor in service! Im due for an upgrade on my other line, but seriously considering moving to another network instead. Can SOMEBODY get my cancellation sorted out and get me some constructive feedback please?
