Global Hospitals Group — Deposit

My father was hospitalised in October 2020 for COVID treatment. When he was discharged your accounts team had taken security deposit of Rs 17000. It's been 6months the money is not yet returned back to me. Everytime I call your team nobody cares to give a concrete response. I have called them several times and visited the hospital several times still my money has not been returned back to me. Please look into this matter as this has become really frustrating. No hospital sits in the deposit money for 6 months.
