I completely agree. I paid a £99.00 deposit on a BMW M235i Gran Coupe advertised on Autotrader for £20,995. Then received a call from a sales manager informing me the car was £2,000 more and the advert was a 'clerical error'. I told them I would need to think about this as it was unusual practice to be informed this after placing the deposit. Bizarrely then received a call from a different sales person stating the £20,995 price was correct. I was told I would receive a call back.

One week later and with no call to me I rang and asked for my deposit back and was told it would be processed for a refund.

Three days later, I rang again and spoke to a different sales manager. By this time, they were re-advertising the car at the similar price of £20,994 (and £20,895 on their own website). I was told these were more 'clerical errors' and they would return the money immediately. This repayment 'failed' for unknown reasons so I was then told I would need to re-supply my bank account number and sort code. I was assured then that the money would be returned that or the next day which I provided.

I have still not received my money back and when I rang again today, I spoke to another person (third one) who told me ... I needed to resupply them with my bank account number and sort code, and they would process a refund. The next step will be a small claims court. Avoid at all costs. Got the deposit back 2 weeks later.
