Harassment From NIMBLE for money that was already paid.

This is a complaint of THREE different Companies. WOOLWORTH, MBD and Nimble. They are asking for money that has been paid already. 2018 I went behind in my Woolworths credit card. Could not pay the full instalment however made a small payment each month. My account was then taken over by MBD. I had a company called Debt PlanToday that was helping me sort my finance out but then COVID hit al that all ended. Then end of 2020 I started working again and started paying towards my account. I could see that they received my funds as it showed on my Credit Score that the amount was getting less. In June 2025 it showed that I only had R1222 left to pay and then I would finally be done. Then I receive a call from this Nimble Group telling me that my account was sold to them and I OWE them R 10 711, i told them that can't be as I can see on Credit score that I only owe R1222. That very next month my Woolworth was closed on Credit Score and a Nimble was added with R10 711. I have since then sent all my proof that I paid more than my credit started and also sent plenty emails to ask for a FULL Statement since 2018 however Neither WOOLWORTHS or MBD is helping and Nimble is sending me statement from only when then got my account or Statements saying I must use my account nr or birthdate but it does not work at all. Mind you, I still have a store card from Woolworths, and they keep call to increase my limit, this is now affecting my Credit score and becoming a harassment. Not one of these companies want to assist me with my FULL STATEMENT from 2018 where I made all my payments.
