Telkoms helpfulness.

My aged Mother in Law gave up her home to move in with her daughter. She cancelled her Telkom number on 9 September 2017 to find it had never been done on 22/10/2018 after being called by the debt collector to say she had been handed over to them. I then contacted telkom and it was recommend I should declare a dispute with which I. I did then contacted the Debt collectors to explain we had lodged a dispute and that must please putthe matter on hold till it had been resolved. On 1/02/2019. I was asked to send them a copy of the cancellation letter. I ended by sending 3 copies of the letter. On the 11/02/19 at 15h00 i was told by the Lady that the service was now cancelled. Then was contacted again by the Debt collectors. So went back to Telkom and was told to go to the Billing Dept which i did. I then spoke to a number of consultants as I was shifted from pillar to post. Every time expressing concern about the debt collectors calls. I was told that in such cases they would lodge a request to have case expedited. I was told to wait for 2 weeks at which I expresses my dissatisfaction. I kept phoning and each consultant after that said they would request for the case to be expedited as there was no such request on the file. Eventually I got through to a very helpful Gentleman who listened to my sad sorry and was prepared to help me. He went int to the file and saw the service had been cancelled on the 9 Sept 2017. He the calculated what the amount was that had to be paid. After deducting all the fees that had never been stopped I was give the amount to be pay which i did. It was a small amount. The matter then was completed and the debt collectors would be informed. Low and behold the whole matter was brought up again that they were on the point of taking her to court. After speaking again to them they requested all the reference number that I was given plus all the reference number on the telephone account which I did. This morning I receive a letter from them to say the reference numbers I had given them were no good for them resolve to problem. So now we are back to square 1 again. She is now probably going to be summoned. I do know what further to do. This is extremely upsetting for an old lady deep in her 80s. Could someone please help with advice of what I should now.
