Telkom deleted a new ADSL line installation with no explanation

Telkom installed a new Line a week back and all was working 100% and then the line stopped working. I phoned over and over this morning speaking to sales, technical and billing. All they do is to say phone technical and vice versa.( 4hours on the line) no one seems to be willing to find out what's going on. One Technical person told me the line was deleted but they do not know why. Also, Sales say it's active and there are no issues.

No service from Telkom anymore? should we look for alternative solutions
