Still no change on account!

This is the third complaint written in as many months regarding the SAME PROBLEM! Since December 2014, there has been a 10GB uncapped internet package on our account as well, which was never requested. Since then we have tried for them to remove it. We have been given promises that a credit will be put through, which never happened. We got a text message this morning that our account is outstanding to the amount of R602, and that our account will be suspended. This, after we were promised last week that a credit will be put through. We have been on the phone to Telkom's call centre since early this morning, but keep getting cut off. We are getting sick and tired of this incompetence and useless service. We have been having problems with Telkom since December 2013, where they can't fix their stuff ups! Why must we pay for their incompetence, where they do stuff that we never requested? I am also getting sick and tired of my requests and complaints being ignored.
