Subaru of Kings Automall

Sales manager provided a lease proposal on an Outback to my elderly parents that was several thousand dollars over the market rate. They unfortunately agreed verbally. Manager required a $375 deposit (unheard of from my experiences) - probably to deter them from seeking proposals from other dealers. I stopped the deal same day. Demanded a refund of the depost. They required my parents to return to the dealership to process a credit to their credit card. Upon arrival, the finance officer initially bluntly refused to refund the deposit then after some argument with my father grudgingly allowed the credit. What a scam. Is this any way to treat a customer in their late 80's? Their position is get the money any way you can and screw the customer at any opportunity. Absolutely shamefull ethics from all possible angles.
