The worst service of my life!!!!!!!!

I traded in a vehicle on 17/11/2023. I was assisted by Shay who works at the dealership. On the day I collected the vehicle I was told by the F&I that I would not be debited for my previous vehicle for the month of November. To my surprise I was debited. I contacted Shay to let him him know and he gave me some lame excuse that the debit order was supposed to go because of how my bank had stricter the deal. I knew he was lying and I kept insisting to speak to the F&I to get clarity. I waited for 2 weeks for a call but nothing. On the 5th of December I noticed VW WAESTGATE had not even paid the bank for the car I traded in meaning I had 2 cars in my profile and my bank had sent me a notification that I would be debited for both cars. Again, I reached out to Shay and he started blaming the clerk for not doing her job. I then demanded to speak to his manager Angus. He said he would sort it and get back to me but NEVER did. Instead he sent his *********** employee Shay to give me some lame excuses again. After 3 days of trying to ge them to pay the bank for the previous car and to refund my money, I drove up to the dealership and was still given a million excuses has to why they haven’t paid the van and why I had not received my refund of R5963. They then asked me to provide them with my FNB acc number so that the refund would reflect immediately. I did exactly that and I still have not received my money. No one seems to know what they are doing they and they all seem to blame each other for not doing their job. Shay is the worst sales guys there that lies through his teeth all day and does not care. He failed to submit my papers in on time for the dealership to pay me and my bank.. I WOULD NOT RECOMMEND VW WESTGATE TO ANYONE!!!!!! they don’t care about their customers at all
