Very bad customer service

Very bad customer service, I tried to call 3 times today but I couldn't finish explaining my issue because all the 3 consultants dropped my calls. I have an issue that my sim card was closed by mistake and at that time there was 25 Rands airtime then when they open it they didn't bring back my airtime. I went to Alberton branch where I opened a contract but the manager said to me I must call 081180 and ask for Gugulethu Mbatha's manager as she's the one who closed my number. When I call all the consultants that I spoke to they promised that the manager will call me since I've been calling from the 6th of August until today. Worse part today no one want to speak to me, they keep on dropping my calls when I'm busy explaining. Telkom 's workers are not taking customers seriously.
