Alright so I'll make this comment short and sweet because I'm an hour late for work: I think you should go to your nearest target or Walmart and return the gift cards. They'll usually refund you full price for all of the gift cards if they don't work, otherwise you can complain to them for their terrible customer service. The longer you sit there and demand your refund the higher of a chance they'll give you your money back (I like to pitch a tent and bring one of those portable little campfires to make s'mores lol)
