Capitec, Blake and Associates and MBD issue

I had 3 loans accounts with Capitec that I was unable to pay due to unemployment. Two of these accounts had almost similar amounts which was seven thousands seven hundred and something and the other account seven thousands nine hundred and something and the other loan had a balance of 37000 and something. The accounts were handed over to Blake and associates. After getting a new job I started paying R500 for each account from the 31 August 2018 until April 2020 when my husband lost his job. In 2019 the balance on these account were R4747.22 and R4678.12 and R34821.14. On September 2021 I received a call from MBD for collection they said the accounts were handed to them by Blake and Associates but I owe 2 accounts. What I don’t agree with is that I owe R7 thousands and something in that other account that was almost the same with the one they said I finished paying even though I didn’t receive a paid up letter. So we agreed that I will pay the for the other account which is twenty something thousands now. I send MBD all proof of payment for all 3 accounts and I thought they had resolved the matter with Blake and associates only to receive a call again last year 2023 in October about this account of which now it has a balance of R9200. I tried to contact Capitec and laid a complaint but did not get help. I also contacted Blake and associates several times asking them to provide me and MBD with the statement of my account showing all payments they received/ deducted from my account, they had failed to provide me with that information saying the account is closed and no longer with them. Today I went to Capitec branch asking for their intervention in this matter but still Blake and associates cannot provide me with with the accounts statement they made a promise to retrieve the records but I doubt so because they’ve been making that empty promise. I need your help I can not pay for something that I know I have a paid and have proof of payments.

I have proof of payments to submit on your request.
