Oyo Rooms — regarding security deposit refund

Address:

Nine gems apartment, adyar, chennai, Chennai, Tamil Nadu

Hi
This is regarding my booking at oyo life in chennai adyar, the code of room was chn1139. Me and my freind joined the room at 1st october 2019 for 1 month. At the time the room was joining was not active on app or website. So we informed our stay supervisor that we will leave after 1 month. He said it's ok. After that stay supervisor got changed two times. I tried to check in through app also, but due to changing or stay supervisor i never got the otp. Now i wanted to leave room due to emergency, so when i asked about security deposit, they are saying it can't be given. Although it was informed to the team that we will leave in one month. We tried contacting life support but they are also not helping.
We were not been infomred by them regarding notice period for security deposit and also no otp was given to us to check in the room by our stay supervisor.
Kindly look into this matter as we are student and that amount makes a huge difference to us.
