No Network coverage

Telkom Mobile Management not interested in solving my Network issue they consistently debit account for no service/no network coverage. 25 April 2015 my query logged again after several complaints, Team Leader Lebo at call centre confirm I was not available, this after I gave them my email address and several contact numbers. Don't bother speaking to a Team Leader as they perform the same function as the normal agent (We will escalate your query) 4th May 2015 Team Leader Lebo confirm his Manager is not in Office, did he leave at 15h20, My no network at home I gave a Temp solution to forward to Telkom Mobile Management not even that was done. Lebo Team leader confirm Technician must first come and investigate, many agents, Team Leaders and my own investigate confirmed No Network Coverage at my address. 4 May 2015 Lebo Team leader also confirm no contact number for Technical they only escalate by email. Why did I sign up with Telkom Mobile, Why,Why,Why
