I am extremely disappointed with the service from First National Bank (FNB) Non-Resident Account division. After I had already submitted my invoices and supporting documents, I was suddenly notified of a change in their rules and requirements. This was communicated after my documents were submitted, which is completely unfair and unprofessional. How can requirements be changed midway through a process without prior notice? Clients cannot be expected to comply with new rules that were not in place at the time of submission. To make matters worse, there is little to no communication. Calls go unanswered and responses are extremely delayed, while my funds continue to be held. This experience has been frustrating, stressful, and financially disruptive. I expect clear communication, consistency in policies, and fair treatment of customers.
