Wesbank HORRIBLE CUSTOMER SEVRVICE!!!

On the 10th February 2023, I made R17 000.00 payment into my VW/Audi Financial services account in error, which I was supposed to pay a dealer for deposit on my new vehicle. I have been phoning customer care regarding the refund, but I'm being taken from pillar to post. I have sent them proof of payment and confirmation of banking details but every time I do follow up its same story that they have escalated my query. It's over a week now and wesbank doesn't want to pay my money back. This has inconvenience me so much as I can't get my new vehicle before paying deposit. I'm emotionally broken, I need to know where I can report them so that they can pay my money back.
