Appellant seeks review of an agency order whereby appellant’s protest of an unemployment compensation reimbursement invoice was dismissed as untimely filed. We affirm the order appealed.

In August of 1981 appellant was mailed a reimbursement invoice which expressly provided that any application for redetermina* tion must be filed within fifteen days of receipt of the invoice. Appellant did not timely seek redetermination, but in February of 1982 advised appellee that it did not consider itself obligated for reimbursement until a “fair hearing” was held. Appellant contends that the agency’s earlier failure to conduct a predetermination interview ren*502ders the subsequent reimbursement assessment invalid. Rule 38B-2.15, Florida Administrative Code, provides that the agency shall conduct an informal predetermination fact-finding interview upon request, and the initial claim notice form advised of the availability of such procedure. Without considering whether appellant was entitled to a predetermination interview in the present case,1 we conclude that the allegation of error in this regard should have been presented for agency consideration, in response to the reimbursement invoice, upon a timely application for redetermination.

Appellant having failed to preserve the issue for judicial review, the order appealed is affirmed.
