How can I evacuate the flat when the agreement is not signed and security + monthly rent is paid?

Hi I was looking for a flat in sector 52 Noida, UP, and had a conversation with owner through No broker app. i deposited the security amount of rs 15000 and rent of 15 days rs 7500. The amount of security was paid in cash as the owner asked to pay offline. While rent amount was paid online in her daughter's account. After shifting the owner made the rental agreement in which few statements are completely absurd. He has mentioned that if i evacuate the place the I have to pay for white wash, which is not my work. he has also mentioned that I cannot change the flat within 6 months and if I do so then security amount will not be refunded. Also he has mentioned that he can enter the premise at any hour, day for the inspection, which is threatening for me. He also entered the flat without informing me and went inside the room when i was in the office as he holds the second key. Both husband and wife enters the house and checks every cupboard even I have put my stuff in the cupboards. They are interfering in my privacy. I haven't sign the agreement yet because I want to change the flat. How can I change my flat and get my security amount back as I have no record or proof that i have given the amount as it was asked in cash?
