Woolworths *****ing money from Loan Account

I had a personal loan with Woolworths and at some point, I could not afford the monthly repayments. The account was handed over to MBD for collection. After contributing payments for more than 7 years, I thought to contact them as it seems this was on a forever repayment scheme. The Woolworths helpdesk informed me that the loan was already settled in December 2022, even though I continued with payments, and they requested me to send an email. I have sent an email more than 21 days ago to confirm settlement and provided my banking details for the repayment. This was done to many different groups in Woolworths. I have done numerous follow up emails and contacted their financial department several times which would escalate my request. Subsequently, I have received zero response from Woolworths confirming that the account is settled in writing or that the repayment is in progress. I believe that Woolworths is acting dishonestly in not responding and not confirming any progress on my request.
