Delayed settlement by Volvo Hillcrest lost me over R10K

In March 2024, I purchased a Volvo CX90 and traded in my Merc 220d. I had to cover a shortfall on my trade-in, which I deposited into the dealership's bank account. However, the dealership delayed the settlement for the Merc with the bank. As a result, the bank debited my account even though the vehicle was no longer in my possession. Despite this, Volvo Hillcrest refused to refund the payment, causing me to lose more than R10K. I want others to be cautious when doing business with this dealership and advise against paying any shortfall or settlement to their account.
