Employees' State Insurance Corporation [Esic] — delay in medical expenses reimbursed since last one year

Address:

Navi mumbai, Mumbai City, Maharashtra, 410206

This is my grievance no: pg19035145

I meet with a road traffic accident in the month of october 2018 due to which i had serious head injury, so i have undergone the 1st surgery i-e decompression surgery and after 3 months have undergone the 2nd surgery i-e cranioplasty in the month of february 2019 in gandhi hospital, panvel (Navi mumbai).
I have icici lombard insurance. Hence i have applied for medical expenses reimbursement through esic for the remaining amount. However i'm asked for all the original medical documents which are already submitted in icici lombard for medical claim, so i'm unable to produce originals to esic hospital (Vashi esic hospital, navi mumbai). But i have the photo copies of all the documents with hospital stamp on it and the settlement letter which states that icici lombard as paid only xyz amount and we are still paying the interest for amount borrowed which is huge for us because it is going to be a year for my accident.
But after 4-5 visits in last 4 months to the esic hospital in vashi (Navi mumbai), they are not a accepting the attested copy of the documents and the settlement letter. They are still insisting for the original document after explaining the whole thing.in vashi esic hospitals all staff are very helpless.
Please do the needful.
