TELKOM DISHONEST

I have paid all my accounts with Telkom up to date and have requested a paid up letter on the 3rd April 2019. I was told I have to wait 10 to 15 working days for this letter. I have called in and the agents have told me that my accounts are paid up. I don't trust Telkom because I have been billed incorrectly before and the data that was loaded on to my modem magically disappeared even after I paid for it. I was told "sorry our agent made a mistake and we cannot give your data back". It is now the 16th May 2019. I am waiting for this paid up letter for over a month now even though my accounts are paid up? This is all because of the lack of admin s****s and staff doing there work incorrectly. I followed up on the following email address ********** Shaun Smith an ops manager responded and asked for my account number which I provided. I have tried contacting him on ********** , however the number is always unavailable. Can somebody please get back to me? I cannot be following up on this case for months on end. Telkom is wasting my time and I am starting to get impatient. Is this the way you treat your customers?
