21 Calls to Telkom for a SINGLE ORDER over 2 MONTH

I placed an order for a new line to be installed during February. Since then , technicians have been out to my house, I have paid the required deposit and and have made 21 CALLS to Telkom. I have had the matter escalated (***) and was promised that my line would be installed within 1 to 7 days. Your call centre agents keep telling me that DUE TO A TECHNICALITY this hasn't been resolved, however, in 2 months the technicality hasn't been resolved!! WHAT THE HELL KIND OF SERVICE IS THIS TO NEW CLIENTS!!!!! This is pathetic!!!
