Tirumala Tirupati Devasthanam — Refund of the caution deposit amount of rooms

Address:	tirumala tirupati devasthanam, Tirupati.
Website:	tirupatibalaji.ap.gov.in

I have booked rooms on at tirupati and tiruvannamalai for the day of 21/09/2021.
the website asked for the caution deposit and will be returned after vacating. TTD is doing a fraud in the name of god balaji and not returning the caution deposit amount after vacating the rooms. I request immediate action, if not will file a case at consumer court.
