Pathetic Service and lack of feedback

I am amazed by the ridiculous service I am receiving from Telkom, when I have submitted such a simple request to cancel a contract that is finished. I am pass the 24 months of the initial contract so I would like to cancel this contract. I contacted the call center and the consultant advised I should go into the store, when I got to the Table View store after standing in a long queue the manager merely handed me a form and said I should contact the call center for assistance. That was quite pathetic. I then submitted this completed form to the cancellations department on the 03/12/2015 and I still haven't received any feedback. I called the call center and all the lady advised is that I should wait for a call from the cancellations department as there is no direct contact number. I did my part by submitting the form with 20 days notice however no turnaround time was provided. All I want is for my contract to be cancelled is that too much to ask?! I'm not asking for special service but merely for some sort of service!!!!!!
