Uber India — Deactivating my all payment methods

Address:	600096
Website:	uber

I am able to login but i am not able to apply any promo codes.It says that my account doesn't have the ability to apply any promo codes.I have already raised this complaint in uber itself but nobody is responding there.Also, they debited money for card verification but still i am not able to pay through my card.firstly, they will start those discount than deactivate the user accounts so that they can't take benefit from it.
