Uber India — unable to book any ride even though proper payment method is given

Address:

Thiruvananthapuram, Kerala

I am a regular user o[censored]ber. Today i booked the cab in the morning and the cab drive has canceled the trip. Again i tried booking through the mobile app but it shows error that it my account doesn't have a proper payment method. But i have a valid payment method and through that payment mode only charges has been taken whenever i opt for cab but today it still showing the same error message.

I tried reaching their customer care toll free number but no one picks the call and always its engaged and there is no support email address where we can address our issues. I don't know what type of support they are running without having a proper customer care.

I need this issue to be fixed so that i can enjoy their service continuously.
