The Circus that is TELKOM!!!

On the 12 October 2015, I initiated a query at Telkom Richards Bay. It is with regard to a contract I signed on 01 August 2015. However, I am being billed a different amount to the one I signed up for. I was given a case number, but when I call the call center for feedback, I'm told that the case number does not appear on the system?? Nobody is prepared to help. I'm just pushed from pillar to post, and transferred to many different people who don't have any clue what the hell is going on. I have sent emails, and I have been to the branch numerous times to check on progress, but get no joy. I speak to the branch manager who says she is waiting for feedback from the relevant departments. I am absolutely frustrated and disgusted at the service levels at Telkom. It's almost two and a half months since I initiated this query and NOBODY at Telkom can sort this out!!!!. How is this possible?? Is there no turnaround time for queries to resolved? This definitely cannot go on forever!!!
