Zero customer service

I have a query since the beginning of October and it is still not resolved, I have called the call Centre over and over and over but no one helps me. My query relates to ***. I have never received a call from Telkom yet I get sms's saying we have tried calling you. on Tuesday I called the call Centre once again and demanded to speak to a manager thinking this would help they put me trough to a lady called Zanele she said she was one of the call Centre managers and she assured me she will help get this resolved and call me back with feedback the same day but I never heard from her after that call... everyone at Telkom is ***********. When will this query get resolved I am getting billed for a device I do not even have due to Telkoms negligence and you don't have the decency to just call me back and sort my query out. I am in tears here as I don't know where to turn to this is the second Hello Peter report regarding the same issue as no one bothered calling me the first time I reported it. PLEASE CALL ME TODAY AND SORT MY QUERY OUT PLEASE PLEASE PLEASE!!!
