Does Telkom ever rectify problems

I phoned Telkom on the 7th April 2015 to let them know that we had been charged for installation of a phone. No installation was done. We went to the nearest Telkom branch and collected a phone and installed it ourselves. They charged R543-86. I then contacted the call centre and explained the situation and they told me that someone would contact me to rectify this and yet I am still waiting. I then decided to call again today and have phoned 4 times. Each time I wait for quite a long period and then I get cut off. So frustrating. If someone reads this, please could you go into Ref No.: ***1 and contact me to arrange a credit in this regard.
