Disgusted

I am at the mall at present. My husband came to American Swiss here on Monday and saw this specific ring marked at R4499.99 - this was in the window with a sign reading white gold and diamonds. So he enquired in store and the person in store confirmed that it is white gold. Which brings us back to the store today to purchase only to be told it's sterling silver. When my husband asked why isn't it with the other rings marked as sterling silver the sales person said they have no place on that side of the window! The ****** nerve! I don't care how but I expect some sort of compensation for this extremely misleading advertising and I expect it today! I have photos proving this! I was excited about getting a new ring today and though it's no fault of my husband he's at the receiving end of my wrath! I await your call
