Uber India — my order never arrived

I was kept in waiting for 1 hour and then the order was cancelled, very very unprofessional behaviour, there is no way to contact support team on call once the order gets cancelled. What about the 1 hour of my time they wasted?
I contacted support when they made me wait 45 minutes and they said it will arrive shortly they could have atleast told at that time, they gave false assurances that they will add 50 credits which is no where to be seen, made me wait 1 full hour and then cancelled order.
