telkom is the worst!!!

i logged an incident in Oct month and it was sorted after being through hell. I was told by the billing dept to go to the nearest store and renew my contract which I did,but when I got there the consultant told me that I do not not have to renew my contract as it is an automatic update and that I will receive my same benefits( 5GB data, 150mb data and 100 minutes) for only R99.00 PER MONTH. I called the call center to double check and was told the same thing. I have the call recorded as this agent spoke to his manager and confirmed that the store was right, just to find on the 04.11.2015 that my invoice for Nov is over R900.00. I refuse to pay this and called in again with my new case number ***7 on the 04.11.15 and the turn around time has expired. (72 working hours). No one has responded or given me feedback and I am sick and tired of fighting with telkom on a monthly basis. I also emailed my cancellation form as I don't want this to happen again.
