Paid up letter?

My homechoice account was handed over to Blake and associates and I started paying in July 2025 by means of a debit order (R1000, 26th every month). In January I received a call from them and my debit amount changed to R1245 from end of January and February. In the middle of March I received a call from them offering me a discount to settle my account which amounted to R3858 and I was debited end of March. In the beginning of April I called them to request for my paid up letter however I was told that my debit is not reflecting and it shows that it was canceled on their side and that I should send a proof of payment. I call again this morning only to be told that my last debit was in December then she then goes on and says I was debited R4000 in January which I have no knowledge of then she says my account has been closed but in the same breathe she says my account has been handed over. When was it handed over and to whom because I've been actively and religiously paying my account with them until end of March and in constant communication with them. They've been calling me however now I'm being told stories that make no sense
