POOR SERVICE/NO FEEDBACK

I am extremely irritated and angry with Telkom as a whole. I logged a complaint in novemeber 2015 and is still waiting on feedback because someone didnt do their job and closed my query. I have subsequenlty logged another query on 10 February and is still waiting on feedback from Telkom. I am being billed for calls and sms that is being made from my modem number and have requested numerous times for the sim card to be capped with no spend limit, however I am still recieving excessive bills with no feedback from Telkom. Is this what you call service? I do not use the sim card for anything other than data, have never made calls and have never sent an sms from that sim, I didnt even know it was possible. If someone could please do their job and call me back with feedback as to when I will get my money back because your \72 working hours\" has long expired and no one at the call centre can give me feedback on my query, all I get is \"they still working on it\". Your URGENT feedback will be appreciate because I cannot keep on paying for calls that I have not made. My next step from here would be to lay a complaint with the Ombudsman because this is RIDICULOUS."
