The number one reason why some Npower Batch C beneficiaries have not received their stipend is simply because of their BVN, please if your BVN has not been validated you will not be paid, once the Npower Batch C beneficiaries' BVN is validated, the Npower Batch C beneficiary will be taken off payment hold and will begin to receive his or her stipend.
The BVN validation process is not an instant process, but once an Npower Batch C beneficiaries' BVN is validated, the Npower Batch C beneficiary will receive payment when payment starts, if your BVN is not validated, even if all your details are correct you will not be paid.
