TELKOM STILL CHARGING AFTER LINE WAS CANCELLED

In June 2018 we moved from one suburb to another. Telkom informed us they could move our line because the new premises didn't have a line. I then requested them to cancel my account as THEY could not provide the service and they agreed. In August and September i phoned Telkom to just confirm that the line was cancelled and they confirmed. Now months later they send me an account saying they are going to hand me over!!!!!!!!!!!!!!!!!!! REALLY!!!!!!!!!!!!!! Yet they confirmed that the line/account was cancelled ?!?!?!?!?!?!? Now i will have a bad name!!!!!!!!!!!!! TELKOM YOU BETTER FIX THIS!!!!!!!!!!!!!!!!!!!!!!!!
