It was very frustating when we can not call uber support directly and register complain. I booked uber and driver took 30-45 mins to come and when he reached near by started asking drop location and after knowing that he started asking me to walk till the main road for the pickup when I denied that he cancelled the trip. I had booked my doctor's appointment but just because of this incident I had to cancel that. I will never trust uber now onwards its last booking from my side.
