Terrible Service!!!

I placed an order for 10Mb uncapped WiFi at the start of May while Telkom was running the R806.1 deal with a free Lit Box. To this day I am still waiting to receive my order. I have had a technician at my house who only installed a land line as he says that was the instruction given to him. When I phone Telkom to have the land line converted to ADSL I get told that I already have an ADSL line. I even got the call centre to speak to the technician while he was at my house who himself told them it is only a land line. To make matters worse, I am being billed for an ADSL line which I do not have. Surely it cannot take a company this long to provide me with a service only you can deliver? Every time I complain I get told my order will be escalated and I will hear back in 48 hours. To this day, I have phoned 18 times to try rectify my order and get what I want. This is totally unacceptable. I need WiFi to run a business and currently am out of pocket because of Telkom.
