In West Bengal banks are providing only cash deposit & withdrawal facilities. No passbook update,new account opening, mobile number update etc non financial services. In our district one women have 70k something in her account but her account is dormant because of this he can't withdraw her money as well as bank employees not doing her re-kyc. Then she complaint to that bank's eastern regional officer. Then branch employees activated her account.
BTW I think you have not visited any bank branchs after lockdown.
