Kokilaben Hospital — Refund Status

My mother was admitted for a knee transplant surgery and she was discharged on 4th Oct 2022.. While the final payment the hospital had kept some deposit amount as per their process and had stated that you will get the refund between 2-3 months. It is more than 3 months and i am trying to reach the hospital for the status since last week but their is no update. Kindly update on the status and refund the deposit amount asap .
