The worst experience with Customer Support ever

I have had issues with my telkom services for the last 5 months (not receiving what I was promised and being overcharged for it) and for 2 months now I have been trying to cancel, I am given wrongful information firstly, find out about the cancellation form which I then fill out and email to them last week already with nothing but an automated response to confirm they have received the request..<br> <br> ALL THE WHILE STILL BEING CHARGED! I refuse to carry on paying for a service that was supposed to have ended already. <br> <br> I have posted on facebook, tried phoning and before the form even going into an outlet only to find out accounts are settled by phone. Even threatening with legal action has done nothing to change their attitude. I am more than willing to remove all posts that I have written about this if an agent will just pick up a phone and contact me to resolve this!
