I have not been able to request a ride for long time and could not find a way to contact them. Finally someone who was uber driver showed me how to initiate chat. My case is refereed to special team who has not contacted me for over 24 hours. I wasted tesla voucher and ended up paying myself. Hope uber will improve their contact method and put a form or something on web site or clearly mark chat on their contact page which is non existent. I ended up using ola and lift on my last vacation. Unfortunately corporate vouchers are using uber more often and thats the problem.
