Hello, I ordered a G5 PC and it's not set to ship yet until at the end of April. It has no invoice yet, and it has not gone into production either. It's only in the "order confirmed" status. I'd like to cancel it however the cancel order button is greyed out. (So is the invoice button.) Why is that? I thought I wouldn't be able to cancel once it's gone into production. Anyone else had this problem? Help is appreciated, thanks.
