Line suspended on a Zero balance..

Telkom has disconnected my services. For no particular reason. I am being constantly told that it's with collections team and suspended. With a R0.00 balance.. If I was to not pay my line it would be a problem.I upgraded with telkom pay about R4000 every month, but still my line is disconnected...I have called 8 times in the past 3 days I have been told system has been down and requested to speak to a manager countless times...This is ridiculous and not on..I have lost contact with my clients..And not being able to make contact at *** Telkom has decided to suspend my line Fully aware that I have paid it fully
