NEW LINE INSTALLED 5 MONTHS AGO AND NOT CONNECTED OR IN USE

Approx 5 months ago, we app**** for a faster ADSL line speed. We were told because we did not have our company doc's with us (the rep from Telkom was doing door to door marketing), it would be put in my name and all would be done within weeks. The technician came to install a new line for the internet and failed to connect this. He even fiddled with our other wiring and our computers stopped working and other electrical components as well. He said he would be back, but never has. I have sent emails to a string of people at Telkom (including the Corporate communication section) and the only correspondence back from them was to copy a whole lot of people on a mailing list and they were requested to follow up. We are being charged R1000-00 per month and the account is only for the service and there are no calls or any other charges because there is not even an instrument! I have requested to have this service cancelled and still, we just keep getting money deducted from our bank. I am at the end of my tether because we are not getting any service and are about R5000 out of pocket for nothing. I want a refund and the service cancelled.
