TTD — Refund of caution deposit not received

Hello sir,

I went to tirupathi on 11th dec 2021. I paid a caution deposit of Rs500 for the room in sapthagiri rest house for one day. At the time of check out on next day that is 12th dec 2021, they informed me that I will get refund of Rs500 directly into my bank acc in 3 to 4 days. But it's been 5days i haven't received any refund. Please look into my concern and hopefully resolve it at earliest.
