cabling departement

I booked my line to be moved from my old house to my new one, first they switched the addresses around then the order was only booked on the 4th October and i know i placed the order on the 19th of September, they did the installation on the 6 of October and the technician told me that is cabling department that needs to fix the error and it will take 7 - 21 working days, we are now on day 21, I phoned telkom sales and all they can say to me is they have escalated the problem and there is nothing they can do, i spoke to telkom's cabling departement who was putting in new cables on the 2nd November and he told me that all the cabling has been sorted out and that we can phone the sales department to book a technician, nobody at telkom seems to want to help me and i would not suggest anybody sign a contact with telkom because of their useless service as no one seems to know what goes on in your account and is unwilling to help anyone, the managers never call a person to let them know what is going on and the call centre agents laugh when you are trying to resolve a matter and i think it is just utterly ridicules
