Thanks Jimmy Boy, I finally got through to the shop owner, who says they check everything before it goes out including the stock, but he says he's going to review the CCTV of him doing it? I told him it certainly wasn't done my end as I opened it on my bed and unless my duvet has some hard edges I've missed, then it happened before I received it.
Hopefully he's not going to be an arse, even if he does I'll send it back straight away via parcel force. It's a shame as it's their last one.
The gun was actually £40cheaper than anywhere else so I'm still tossing up if i got a good deal ev
