Oyo Rooms — oyo doesn't allow me to delete booking history

Oyo doesn't allow me to delete booking history either on the app or even when i have called them multiple times. This is a privacy issue and oyo doesn't seem to be bothered even after multiple requests. I'm greatly aggrieved and want my details removed immediately so it doesn't fall in wrong hands.
Such data can be used to blackmail unsuspecting people and fraudulent transactions too could happen
