Complaint Review: Royal Carribean

My wife looked at gold chains onboard the Royal Carribean Liberty of the Seas. The sales lady told her they were solid gold.  I said that they were a good price for solid gold and the lady cut a piece of chain to show me they were solid so we bought several pieces.  After a month of wearing the bracelets that were custom made for us the gold wore off and turned my wifes wrist black.  Royal Carribean of course passed the buck and told me to call Starboard Cruise Services.  I have not called yet but have little hope as they require the original sales receipt.  I'll report if they give a refund or not.
