GG, ask them for a recording of the telephone call. They cannot demand payment as they do not have your signature. You also need to know where the telephone call originated (if you are lucky, it will be when you were on holiday in your caravan so you can prove it was not you. As they do not have your signature, they cannot demand payment, although you must send the nasty cardigan back. Check your bank statement, just to make sure they haven't got bank details, but it sounds like the bill is a request for payment. You know you didn't order it, especially as it's the wrong size.
It could be someone you've upset sending this to you as a nasty dig, just to make trouble for you.
Ring them back, have a rant, ask them to ferret out the recording, and you need to know the date & time it was ordered, and the telephone number it was ordered from. That might give you a clue of who it was. They don't have your signature, so they don't have any sort of agreement with you, therefore as long as you return the goods they have no legal comeback on you. Make sure you get a proof of postage (free) from the post office, although you will have to pay return postage.
If they get stroppy, get stroppy back. Check your bank details. Invest in a shredder and put all of the shreddings on the compost heap. I'd also go and get some advice from Citizen's advice. Hope you get it resolved, getting things through the post with a 'congratulations, you've won X in Y competition' is great, getting stuff with no explanation is worrying!
