E on[protected] through uber, the same has been accepted by driver and called me that he will be at location within 5minutes, but after 10mints he cancelled my trip without any information, again i booked next trip for the same, but thrice they have cancelled my trip and charged cancellation charges of 47.5 thrice, after my complaint the amount has been credited to my account. But, this uber # has wasted my 1hr time and i missed my examination. Uber is responsible for my failure in examination.
