<prompt> Human: Back in August, I bought a 25 Amazon gift card at Whole Foods. I sent it to my friend as a gift only to be told that the card didnt work. So I tried entering the card myself and lo behold it says that the card is not valid. I have my receipt from Whole Foods, proof that I had purchased it from them. However, WF is saying that they cant do anything and that I should contact Amazon. Spoke to an Amazon customer service rep for about an hour last night. He basically informed me that the card had been killed but wasnt able to offer me a resolution. He also informed me that the card had been purchased at Black Hawk, which is news to me since I purchased the card from WF and have the receipt as well as the credit card statement to prove it.At this point what are my options? I filed a dispute with American Express and now waiting to hear back from them.Has anyone had a similar experience? Ive purchased dozens of gift cards over the years and have never had this issue before. Who the heck is Black Hawk? Is this a scam? Any help or advice would be appreciated  <response>: I would Keep bugging amazon on chat and escalate the issue...threaten to dispute with CC, offer the proof you have. If they do nothing then file dispute.
