I was finally able to get someone at Uber customer support in India to assist and give me the credit for my gift card. Don't throw away the card and keep trying until you find someone at Uber who will help. Once I found the right person to help it went quickly and the credit posted within minutes. I often wonder how much business is lost due to idiot management at large companies who outsource their customer service departments to the cheapest outsourcing companies they can find.
