Complain on the settlement account of my traded in vehicle

am writing to formally lodge a complaint regarding the delayed settlement of my trade-in vehicle by MMU Klerksdorp. On 31 January, I traded in my GWM P-Series (Registration: LMF 369 NW) for a GWM P300. As part of the agreement, MMU Klerksdorp was expected to settle the outstanding balance on my previous vehicle. However, to date, the account has not been settled. As a result, I am now in arrears on the old vehicle account, and the bank continues to contact me regarding missed payments. Furthermore, debit orders are still deducting.This situation is unacceptable, as I have already fulfilled my part of the agreement. The delay in settlement is negatively affecting my credit profile and financial stability. I kindly request the following urgent actions: Immediate settlement of the outstanding balance on the traded-in vehicle Proof of payment confirming that the account has been settled Reimbur*****t of any debit orders deducted after the trade-in date Written confirmation that this matter has been resolved
