I had to call Giftcardmall customer service last week about a card that wouldn't activate. The person who answered was patient and walked me through the process. After verifying my purchase details, they issued a replacement. It took about fifteen minutes on the phone, but the issue was resolved without any hassle. I appreciated that they didn't try to upsell me or make it complicated.
