Send my paid up letter!

They handed me over without following the right procedures according to the consumers protection order after failing to take in my phone for repairs. No letter was sent to me and I wasn’t given my 21 days to response. I just woke up one and through my FNB found out that I was listed. I paid off their account but their Hammond and Pole people still didn’t send my paid up letter. They were so quick to list me without informing me but now that I paid, I have to exhaust my resources by calling everyday requesting for a paid up letter so I can clear my name but no one is sending it. Even spoke to management and they confirmed that the payment is reflecting but still, no paid up letter is sent. They are inconsiderate and ruthless when dealing with customers. Our airtime and data disappear and we not got compensated for that too. Send me my letter!
