GAS AGENCY SAYS THAT IT IS THE DUTY OF BANK TO CHANGE. DUTY OF GAS AGENCY IS ONLY TO LINK AADHAR. THIS IS CONFIRMED BY IOC ALSO. i was initially getting subsidy through Kotak bank. I had inoperative account with Bank of India. when bank of india wanted my aadhar details I provided. automatically my subsidy bank was changed to Bank of India. Without seeing this I closed the bank account. since Dec 2017 I am not getting subsidy. all my existing SB accounts with other banks were already aadhar linked accounts and now they are not in a position to again link the bank account for getting subsidy. Please tell me how to get subsidy in aadhar linked existing accounts.
