Worst Service Ever

I actually feel like a fool in doing this but it seems the only way . I have made contact with you call centre on numerous occasion and I have never been satisfied with the answer that I receive however this is now the last straw. After trying more then 3 times as to why I am receiving sms's stating that my account was in arrears knowing that I made payment via EFT , Khosikani from customer service advise that there and amount of R39.00 that was not paid, so instead of paying R785.00 I paid R750.00. no one could advise that there was a shortfall of R39.00 but advised that my account was in arrears of R783.00, I then paid in the R40.00 and emailed the proof to them but still to date I my lines are still suspended. I asked the client services if they could not activate it as I use my line for business but all they say is that they are not able to assist and I need to wait 72 hours . this to me is not customer service but a useless service provider. you never find a MANAGER TO SPEAK TO AND ARE FOREVER IN MEETINGS OR NOT THERE ..... TELKOM YOU HAVE MUCH TOM LEARN IN THE SERVICE INDUSTRY
