Wrong light cover included. Bought two Windward II Gossamer Wind Series at Home Depot months ago

Question

Bought two Windward II Gossamer Wind Series at Home Depot months ago for a home under construction. Never opened the box until recently and after we installed we were ready to put the glass cover on the light of the second fan only to find it was the wrong one in the box. No longer have the receipt and would like to order a replacement glass to fit. Any ideas? I asked at the store where purchased and they said they couldn't help other than to try online.
