They lost my amp

I'm hoping you guy's can put me at ease. I bought mono-blocks from an Agon member. The shipper managed to deliver one mono-block but lost the other. They put a trace on it and said we must give them seven days to find it. My question is: When they lose these things, do they usually find them or is it like the police looking for stolen property - it's probably gone. It's been missing one day and it's big.
