United India Insurance Company [UIIC] — claim not received claim no hh[protected]

Yashoda amin s eye surgery was done on 10th september but till date refund has not been received. Multiple emails have been sent by us but no response. Multiple phone calls have been made but always a negative response from the team stating system issue. Does the claimant need to wait for 3 months for the claim to be settled. Is this the way the co treats us.
