Shalby Hospital - Extra Money deposited at Shalby Hospital Not refunded after 1 month

I have deposited ***** at the time of admission of my Mother for Covid Treatment But i have insurance so the treatment need to be cashless. Hospital got the approval from Insurance company after deducting *****, so hospital people said that your remaining ***** Rs will be refunded in your account in few days. After * weeks when i called them then they said that it usually takes **-** days to refund the amount and now almost after one month i called them for refund so they are saying, we will refund once we receive the amount from the insurance company and no one is talking properly. Please help me out.
