SBI — Unfair Service

I have a policy in SBI Suraksha policy NO:[protected], as per the policy I need to get 600, 000 coverage, prehospitalization, post-hospitalization, single a/c room.
But they refused to give me a/c room, pre-hospitalization, and post-hospitalization.
As per the cash-less claim Hospital people are not allowed to give the original bills but SBI health insurance team keep on asking me to provide non-related documents keep on changing their words.
I submitted all receipts and the Hospital admin team already submitted all the bills.
SBI cheated with several promises but they failed to keep the promises
