National Payments Corporation of India [NPCI] — aadhaar seeded with bank account but not updated by npci

My father's aadhaar number[protected] is seeded with his one and only bank account number [protected], on 18/10/2017, maintain in uco bank, kakching branch, ifsc code - ucba0002999. Despite that it is not updated by npci till date. I have tried dialling the npci number *99*99# many times but it always says the aadhaar number is not linked with any bank account. Our local lpg distributor is prohibiting to book for or receive refill cylinder as the same is not updated by npci. We have visited the bank branch and they say they cannot do anything about non updation by npci. Please redress the grievances. I have to raise this complaint on behalf of my father who is semi-literate and he is feeling helpless and harassed.
