Payment Misery!!! I seriously hate Cell C or their partners (I don't know) NDS Credit!!!!

I'm writing on Hellopeter with the hope that my misery will be over! I don't know what to do anymore! I have fully paid my Cell C account and have just receive such a message yesterday from NDS Credit that reads: "Start 2019 debt free. Settle your account and have your Credit Bureau profile amended. Call NDS Credit Management today on.... Ref:..."

I don't know how Cell C or NDS Credit work, but I don't even know what is the suitable word to explain how they work. Cell C handed me over to Shapiro Shaik Defries & Associates (SSDA) bcoz of my account problems of which I fully paid my account which had a balance of R1500. I paid this amount to Cell C via their Shapiro Shaik Defries & Associates debt collectors on 30 September 2017. After a while, having made the payment and confirmed with SSDA I was contacted by NDS Credit people again and again that I'm owing Cell C and have to pay this R1500. I sent the proof of payment to NDS Credit again (Nov 8, 2017) and again (29 Nov 2017) and again (09 Feb 2017) and again (12 March 2018) and again (12 March 2018), until I reached an NDS - Call Centre Supervisor by the name of Mr. Neo Lebyane who responded by saying, "Proof of payment has been received." Since I was requesting for the paid up letter I requested him for it as well, and this was his response, "I have taken this up with Cell C again hence they have had advised that , the paid up letter will be forwarded to you directly." The paid up letter was never received and today I am receiving this message: "Start 2019 debt free. Settle your account and have your Credit Bureau profile amended. Call NDS Credit Management today on.... Ref:..."

Please guys, I've got enough misery of my own. Sort out the way you work. I don't owe Cell C and I don't understand why I should be receiving such a message!!!
