SERVICE NON EXISTING

We app**** for the 10 mbps 50 gig line in April. Technician came out and installed 4mbps. Called them to rectify. Telkom cancelled the order and sent me an invoice. I logged a dispute and placed a new order. Technicians came out again, but nothing worked. He said he can't help me further and I will have to call the call centre. Called them and they can't help. Literally spent hours in the phone. Apparently they keep escalating the call and promises that someone will call me back. It is now July and we still have no working Adsl line. I have called numerous times and spoke to sales, technical you name it - lost count. Went to the Telkom shop in Northgate but NO ONE can help me as the username and password that Telkom gave me does not exist. Terrible attitude from staff all over and not to mention that I keep receiving an invoice. I called again this morning to find out that our order has been mysteriously cancelled. AGAIN.I WILL NOT PAY FOR THEIR MISTAKE and hope that someone can get back to me to sort this out. Telkom specialises in wasting people's time and testing their patience... Not sure what to do anymore and desperately need the Line!
