Uber India — the inconvenience and cheating o[censored]ber

We booked an uber go fro pick up from the airport. It was showing a fare of about 116-150 rs at the time of booking. 5 minutes later we received a message saying that due to high demand, tge the fare has increased to ₹350. We tried to cancel it but it said that it had already arrived. We had ordered a small uber go but it senr a big car. We had to pay a fare of ₹350. We also did not receive the bill. This has happened to us many time. At the time of booking they show nominal fares but then change them at the last moment and we r unable to cancel the ride. We have not received any invoice or detail of the fare. We are tired of this policy o[censored]ber. We are very angry by such type of monopolistic and unfair practice o[censored]ber. Kindly look into the matter.
