According to a communique sighted by Hypercitigh.com, the management of the National Service Scheme says it has duly paid the May 2021 allowance for NSS personnel.
NSS Personnel note that payments are made based on approved list recieved from your employer. Enquiries regarding non-payment of allowance should be directed to the National Service Secretariat.
NB: Your dashboard can show processing while you have been paid. Hence, it advisable to go to the bank to confirm payment.
