Citibank Prepaid Card Complaint

Citibank Prepaid card department,

General purpose card Fraud or scam Connecticut

I returned several items to my local Home Depot on - -, 2016 that I had purchased using Visa prepaid card number - - - -. Home Depot issued a credit for $39.00 to the prepaid card. The problem is that because the card had expired in - of 2016, two months before Home Depot issued the credit, there is no way at all for me to retrieve those funds. My question is, why does the expiration date not show up when a store attempts to apply a credit to an expired card? This seems like a scam for the prepaid card companies to knowingly get funds that the customer has no way at all to access.
