More than 40 days awaiting paid up letters

Over the years I just come to a realization that some companies will never reach their full potential or highest level due to the lack of after sales service, I had a contract with cell c it commenced in 2017 and 2019 July the contract ended, I went to the store to close off the contract, they told me they will deduct one more time and the contract will be closed, fast forward to 2020 July I get a call from Blake's and Associates, alerting me that my account has been handed over, I went back to cell c to ask what was going on, I was told that I need to give 30 days notice, I then requested my for a copy of my contract, a consultant named Paul from Middelburg Mall Mpumalanga told me that I will never get it coz it's at the warehouse, I then left and then on the 30th December 2020 I settled those accounts coz I was already listed on LTC, early January I contacted Blake's and Associates to request for my paid up letters, they told me they will send a request to cell c to ask for them, I waited n waited, towards end of January I contacted them again and they told me there is a delay from cell c, I contacted cell c they kept on hanging up the phone, putting me on hold, fine I decided to go to the store as I wasn't getting any help because I kept on asking them where can I get them, so they can give me contacts for that department, they told me there isnt a department for that, okay I get to the store at Middelburg Mall Mpumalanga I spoke to the same consultant named Paul he called and they gave me a case number, the next day I called to follow up on the case number then I was told that there was no case logged that's a reference number for the call, I then went back to the store, then I spoke to a different consultant as he was helping me, he said that they don't have Blake's and Associates details, I quickly went to go get the number, when I got back he was busy with another client and called his Manager his name is Justin or Justice , I told the manager my story he literally laughed in my face and didn't know the Blake's and Associates worked for cell c, but okay he said they can't help me, I asked to speak to his regional manager Maralize and she told me that there is nothing she can help me with in my case, she said the only advice she can give is that I contact hello petter maybe I might get help, I'm not really a guy that likes complaining and all that all I need is my paid up letters that's it because now my life is in hold because of that, it's really really frustrating, in a moment I regret signing and using cell c service, I'm really tired of this issue.
