Extremely poor service and empty promises!

On discovering that my data connection has been disconnected, I made an enquiry to the Telkom call centre which I then explained to them that my bank account details has changed which is the reason y I've been behind with payments to my data contract as they have been debiting of my old bank account. After updating my details on their side, they told me it will take 7 days to reconnect me to the Internet again. After the 7 days there was still no progress. I then called again. Telkom told me that now it will take 2 working days till I'm reconnected again. Still nothing! I then contacted Telkom again. Once again, another story. It will take 24 hours to reconnect me they say. I really do not have faith in them and their empty promises. I even considered upgrading my contract with Telkom, but after all their empty promises I will not upgrade and I don't feel that I want to continue my contract any longer. Poor poor service!
