Uber India — Booked a XL cab but sent a sedan

During this pandemic in big citiea like banaglore it is difficult to travel so you book cabs . I have booked a uber XL cab from my place Sarjapur to vaccination center Jayanagar where 4 people are allowed. So we booked a XL cab(so as to accommodate 3 people) instead of other sedan cabs(where only 2 people are allowed) and when the cab came it was a cab where only 2 people were allowed and the charge he took was same . When I checked with driver he told he got the booking. When I try to complaint there was no option to communicate or complain.My only concern is if you have no cabs then you should have not taken the booking . We have booked the cab because we are 3 people and after waiting for cab to arrive after 20mins we see wrong car is sent. This is really frustating for a consumer to get cheated like this and do nothing. At the end we have to book 2 cab and go with the cab at same premium price . I want some kind of rules to avoid this kind of cheating.
