Its Blackmail to customer. This app promise you to give a n AC room but Hotel owner provides Non AC room and He will misbehave with you for that. When if you call to customer care for that then customer care will confuse you, if you repeat again your words then customer care will disconnect your call after that you will lose your money, So be careful with this app. OYO is only a famous brand but their work and behaviour is bad. So be careful.
