My family buy a lot of clothing from Macy’s near my home, and we use bank credit card points to exchange for Macy’s gift card and we also have many macy’s return store credit card when we return. Today, before we went to shop at Macy’s, my wife told me to pick several of those gift cards or return cards, I checked about 8-9 Macy’s card and found 6-7 with zero balance, so I threw them away, and took 2 cards with balance to go to Macy’s with my wife. I purchased 2 pants and when we used the one with balance to pay, the cashier told me there is only $1.51. My wife was surprised, and asked back the card after we use the $1.51 as part of the payment because she could not remember any card with such low balance. After we came home, we called 800-511-2752 to check the activity of the card 8361654347112098421, we found following transaction: my wife got this card as a return credit of $194.45 on 11/30/14, my wife made $128.62 purchase online on 8/24/15, and 3 days later, my wife received an email that one of the 3 items that she ordered is out of stock and Macy’s would issue a credit of $42.51 back to the gift card, but Macy’s actually charged the gift card $42.51 on 8/27/15 instead of refund. so we paid $42.51 twice for a cancelled item,leaving balance only $1.51, and $21.81 missing. We called Macy’s, Macy’s customer service – Jenny Luin and her supervisor – May told me that they would check it and recently something something was wrong with their system. We are so shocked with the Macy’s system, we never thought the calculation and operation would be wrong. My wife estimated that the 6-7 gift cards that I threw away could add up to around $1,800 – 2,000, but because their system went wrong and I thought those cards had zero balance and threw them away! This is ridiculous!!!
