For taking Amex credit card, I was promised a INR 500 gift voucher of BookMyShow. After few months of receiving the vouchers when I tried using it, The message voucher is already used was displayed.
I contacted the sales team who came to our office and she assured that she will look into it. But even after repeated followups since two months no response from the Amex team with whom I signed up.
Other services of Amex are good except signup gift.
