unhappy with service

I'm very upset about the service received from Telkom, from before the 1st of Feb 2015 I did not get any internet service from them. I did more then one attempts to contact the call center and went to the shop in Bayside mall where i was told that they not the call center and cant help but log a complaint. a technician was sent out to help with my problem, when he left he said that he cant fix it. I was still left with no service, at the point of being irate i canceled my like and was told my bill will be adjusted, still i get a bill saying i owe almost R1300!
