Uber India — offers fake declared invalid

Hello there. I got promo code from uber that expires on 28/8/17. On my last two trips when i tried to apply promo code it showed invalid. On one side uber alluring customer by offering 50%off on rides and on the other side code is not applicable and declared invalid at the time of payments. It's a unfair trade practice. It's not expected from uber like reputed company. So refund my money its not fair to cheat regular customers.
