Sir, I have account in SBI Vayusena Nagar Nagpur (SBIN0003678). I have submitted a NPCI aadhar linking request form for mapping my Aadhar ( Aadhar No.[protected] . However, the bank is saying that aadhar is linked with the bank and mapped in NPCI, but I am not receiving my fellowship amount since the payment is rejected by NPCI for the reason: Aadhar mapping does not exist/Aadhaar. .
This is happening since last two months. Now what should I do? Who is at fault?
