Kokilaben Dhirubhai Ambani Hospital — Deposit not received back

My dad had been operated on the 17th of Feb 2021, on cashless for which the hospital had kept a deposit If rs.22973, which was told will be refunded on the claim settlement, it's been long the claim has been settled with the hospital but I haven't received my deposit yet.
Tried following up with the hospital but not reply on the same. Please look into it.
