Reserve Bank Of India [RBI] — state bank of india ppf account settlement

Address: t/2 gulmohar complex,111 modi,saat rasta solapur, Solapur, Maharashtra, 413003

Re sir,
My father mr popatlal nanjibhai patel had a ppf account in state bank of india, treasury branch, solapur since 1998. The account no: 01p[protected]New account no:[protected]) bank issued a new passbook dated 05/04/2010. There was a nominee mentioned in old passbook whereas in new passbook there is nothing mentioned about nominee.
My father passed away on 26/12/2019. Today i had visited in the bank with the passbook and death certificate. I was said there is no nominee in the passbook so i visited again with the old passbook. I visited 4 times in a day for the same thing and was already there for 3 hours since morning just for the sake of claimant form which got wasted. I met branch manager as well (Mr randhir kumar singh).
When i requested for the claimant form i was asked to come in the evening by 6 pm or else tomorrow morning.
The passbook is to be updated by the bank and according to me its their duty.
The above account matured on 31.3.2019 and we had given a application on april 2019 to extend for 5 years this account. It is also mentioned in the passbook.
We are already not in a mental state and we are been harrassed alot by the staff and manager.
Please take some action regarding this issue.
Thanking you,
Sanjay patel
