Pathetic Service received!

Firstly, I would like to express my total dissatisfaction with Telkom Mobile. I previously had two contracts which ended April 2015. I requested a cancellation of the one contract and an upgrade on the other one. Hence, I received a few calls from different consultants from the call centre regarding the cancellation confirming that it has been logged and cancellation is in process. Today, two months down the line, Telkom mobile is billing me for the contract that was supposedly cancelled. I refuse to pay the extras.I called them today and it was confirmed that i need to fill out cancellation forms and forward it through to them which was not ever explained to me. Previously, there were other cases where specific information was not disclosed to me on many occasions. Ive been having problems with Telkom mobile since day 1 that i have been with them and i regret ever taking out a contract with them. I would not recommend this service to any individual out there. Telkom Mobile service is pathetic in all areas of their service.
