Appalling service at Telkom.

I requested Telkom to terminate my account at the beginning of March 2018, I completed a cancellation form at their store and thought all was done. To my surprise, at the end of the month I received a telkom bill as normal as if my account still existed. I made a follow up through their call centre line. They had no clue what I was talking about, there were no records of my request to cancel the account. So, I had to do it again. I resent the same cancellation form that I had sent in March. Again at the end of the month the bill came indicating that my account was in serious arrears. I have basically made numerous follow up through emails and by calling the call centre line, but no one seems to know or perhaps willing to address this matter. To date the account is sitting at over R1000. I am now actually having two telkom accounts of which one is redundant.
