7 cards and none of them work!
WILMINGTON, DELAWARE -- I have been a customer of the Frontier Airlines MasterCard for several years. Two months ago, they sent me a new card, telling me that they have upgraded my card from the Platinum to the World card. Only one problem - the card won't work! I have called them numerous times, and they have now sent me SEVEN cards - none of them work! When I call in, they just tell me that it shows approved on their end. But the purchase won't go through! They say since it works on their side, there is nothing they can do! I fly Frontier a lot, and like that I can accrue miles on the card. But I am frustrated beyond all belief.
