Colive — Rent billing issue

Address: House No 337/2nd Floor, Block L-Extension, Mohan Garden,Uttam Nagar, New Delhi-110059

I am a tenant of Colive Sunrise. I am recently moved to Bangalore. I thought Colive is a better place to stay near to the main road So, I took a room for rent here. Now suddenly after 3 months, they increased the rent from 11k to 14k, and when we asked why you increased this much rent that was without any prior information. They are like we have not increased the rent from last 6 months so we increased. Now I want to vacant my room because I am going home. I was trying to raise the notice period but It's showing your remaining balance is 9K. I don't know why their app is showing basic rent 22k now. I have already raised the case many times for the same. I know they won't refund my security deposit. The thing is that I am not able to raise notice which means if I vacant my room without notice they will send the court letter to my address asking for the sum of rent. They already did it to my friends. Please help me.
