It's really getting to the point where buying online isn't worth the hassle anymore in my opinion, and if I weren't disabled, I'd go back to shopping in town. To be on the safe side, you need to be in and watching out of the window from the day after you place an order, until it's delivered into your mitts, as turn your back for a minute, and they've put a card through the door saying unable to deliver, or you get a message saying they've delivered, but you can't find it. However, they've managed to take a photo of it on your doorstep (or possibly someone elses), and then some bastard follows the van, and nicks the parcel before you've had a chance to open the door. If you should manage to get through this stage, you then have to film yourself opening the parcel, to ensure you can prove that you've actually received, (or not), what you were supposed to have, and then, after OP's experience, it seems you now have to photograph or video every little part of the item you've ordered as you get it out of the package, and before you use it, or try in on, in case it needs to go back. Then if you don't like it, or it's damaged, you need to video yourself re-packing the parcel, and sealing it up, before you can send it back. Oh, and of course, if it's collected, perhaps we should be taking a photo of us handing it to the collector, to ensure we have proof of who we gave it to! What happened to online shopping being easier???
Sorry, went off on one there, but I do hope you'll be able to get your money back OP, and if not, that you are able to put this experience behind you, and enjoy your wedding. Hope all goes well.
