Telkom Contract Age - 1+1 = 4

I am sick and tired of the people at Telkom constantly *****ing up my contract. I have complained on numerous occasions that my contract period is incorrect. Amazingly enough, your system shows I upgraded in December 2016 to my new contract and 2 years down the line, when my contract is about to finish, I get told my contract only finishes in December 2019 as it is only 11 months old. Every time I call in, the consultant escalates it to the back office (which I think is a bottomless pit because nothing ever happens there and nobody gets back to you) and then a few days later I get an sms saying my case has been investigated and resolved. When I call Telkom back to find out when my contract ends, nothing was resolved and we go in circles once again. So my resolution to this problem is that I will not be paying the Telkom bill like I normally do, and in the process, my Telkom Wifi contract is going to get cut as well. And don't let me get started with the hacking on the Wifi. Telkom must then only think of handing my over. All hell will break loose then!!! For a huge company like Telkom, your sevice is pathetic to say the least!
