The company with no customer care, TELKOM

I am trying to speak to somebody regarding a Telkom Bill, every month I get an invoice for services, I don't have Telkom lines for more than a year. I have forward mails to everybody that said to me they can sort this out. The so called, I am the only one in Telkom that can give you credit, just never returns my mails. The another so to say important women phoned me regarding my account, o please send me all the communications up to date and I will sort it out. Then the technician comes to collect the instruments, but he knows the problem I have from day one, he then took the copies of the conversations with him and forward that to his connections and they did phone me back, but I just got a brand new invoice of over R11 000. You try and get hold of the CEO of Telkom, his mail comes back and you are back at the dead end. Nobody in the billing department has the qualifications to understand what is going on with my account, They said to me that they can see that the lines were cancelled, but somebody reinstated it and the don't stand pa for that. I think this is very bad from a company that are loosing 1000's of clients every day. There is no customer care at Telkom at all!!!!
