About two weeks ago I stopped by a B&M jewelry store since I was on the market for an engagement ring. I knew very little about diamonds and just wanted to get educated. I've seen commercials for the store and they seemed trustworthy. Well I went in and got the short education and was shown diamonds/rings. I knew the shape, carat, and setting style I wanted so they showed me a few options. I found a 1.02 G SI2 with a clean table that I did like well in my price range. Long story short the sales lady puts on the car sales hat and says this diamond won't last long. I was very weak and she told me just put $500.00 down(normally $750.00) deposit on it to hold it on layaway. I didn't like the feeling after leaving and of course find pricescope.com after getting home. All the knowledge and different places to buy. My question is now the receipt says no refunds for layaway. I know they will put up a fight after reading reviews online of them. Am I screwed out this money(store credit) or could I do a chargeback with credit card? I'm in possession of nothing. Thanks.
