National Payments Corporation of India [NPCI] — Bank details not visible on aadhar website

Address:

Ballarpur

I have visited SBI branch and linked my account for DBT. I couldn't see my updated details on aadhar bank mapper site. It still showed my previous bank account which was closed a year back. I revisited SBI branch to check if aadhar was linked and the banks employee said it is linked from there end, which meant the NPCI mapping was not done. The UIADI website fetches data from NPCI so my account is still not mapped and since I have already approached bank and raised a complaint I am not sure how to reach NPCI. Also I don't understand how a closed account can be linked to Aadhar. Due to all this my scholarship was not credited to my account and even now I am not sure it will be credited as I don't have any confirmation if my account is enabled for DBT.
