****ty Service From Telkom

I have been trying to get my paid up letter since the 11th of June. I app**** for a contract sim online in May last year and the sim card wasn't delivered for about 3 weeks so i went to the shop in benoni and app**** for another that i could get same day. A week after that the sim card that i app**** for online arrived but i didn't want it anymore since i had a contract already but the courier guys told me they are just delivering i had to take. I took the sim card to the store in benoni to let them know that i didn't want the sim card anymore and they told me its not active. The following month the statement came showing 2 contracts that i had to pay. I then went back to the store to inquire about the second contract since they told me it wasn't active and they called customer care for me and i was told that they will fix the problem. They deactivated both my accounts and they said they are investigating. Two months past without them saying anything about the investigation and so i got worried and phoned customer care to find out what was happening and they said its still under investigation. I asked them how much do i have to pay for the contract that i took from the store since it was active for the first month and the said they can't tell me since there's an investigation going on. Six months later i got an email from a collection agency(nudebt) saying i owe telkom R2995 for services provided and that surprised me since my contract was for R250 and was only active for a month. Since then I've been trying to get them to tell me how they got to that amount and they can't give me answers. i called their customer service maybe 50 times and still they couldn't help me. They eventually reduced the amount to R2119,02 which they still couldn't explain the reason for the new amount. Since this was affecting my credit score badly and i needed a clean record so I can apply for a bond, i decided to pay the amount and forget that telkom even exist. I paid this R2119,02 on the 11th of June and requested a paid up letter. Its the 30th of July today and I haven't received the paid up letter instead i receive calls from nudebt collection agency saying i owe telkom another R1750,45 yet when i call telkom they confirm that i owe the nothing. Their customer service consultants keep telling me that they escalated the matter but they can't help me more that. If telkom doesn't solve this problem, i'm expose them to every social media i know.
