Terrible service

We have a adsl line with telkom, we have moved and booked our move of the adsl line a month in advance. We received confirmation that the new installation would be on the 1st of October which was fine as that was out first day in our new place. When the first arrived we received a sms stating the installation had been moved to the 6 th of october due to a exchange problem we made all the arrangements and yet no technician came out or even called. Calling the call centre is a waste of time as you hold on for more than a hour and still get no service. We need our adsl to be installed asap as my husbands business all comes from the internet and e-mails. Please i have paid for my services in advance and now i cannot even use it.
