Payments not received by beneficiary

Made immediate payments to FNB beneficiaries and payments never went through to them. On enquiry they did a track and trace and could only advise the funds have been cleared from my account and advised that beneficiaries should follow up with FNB.

FNB advised beneficiaries to go back to payer. 5 days later funds have still not been received and appear to have been lost in the abyss. Nowhere else to follow up.
