I still don't understand how the OP has no OEM hood? What happened to it? It's not ARKYM or PYSpeed's fault that he doesn't have his OEM hood to put back on while he ships the CF one back. He was offered a refund and a shipping label to ship the hood back. I don't understand what more they can give him at this point.
It definitely should have been handled differently by the vendor and the manufacturer but we're way beyond that at this point. It seems like the big deal here is the OP doesn't want to ship it because he doesn't have another hood to install but I don't see how anyone else can be held accountable for that.
