[求譯]"if one is due"的翻譯

[ca1 (卡一)]

最近在回一封mail

主要是提到我們必須快點作出決策以防任何風險產生

原文有一句提到

It is important that you contact both of the

following individuals as soon as possible regard your decision.

Arrangements for a refund, if one is due,

can also be made with Ａ先生 or B小姐.

想請問文中的"if one is due"這句要怎麼翻譯比較恰當？

感激～

→ ca1:所以也沒什麼特別的意思？了解～謝謝！
→ DarkD:one指前面的refund。第二句前半大概意思是如果超過退款期限
