[BUG] Credits didnt refund if item has plans

Hi, I had issue that if i config the item which has plans options like 1 day, 7 days, 1 month. Whenever i sold an item it did disappear from my inventory but I didnt get my credits back. It only happen when the items have plans. I did sold an item without plans (pernament expiration) i got no issue and my credits did get back. Please help
