At face value there is no actual evidence to suggest it is anything other than a monumental c**k up at this stage, so little point reporting it to the dibble as they won't record a fraud. You've certainly not been a victim of fraud (that we know of...yet) so you're not a victim, ergo no crime until someone else approaches the police who has suffered a loss.
I would suggest....
1) Email the firm, explain you didn't order it and they should come and collect it at their expense. Give them 14 days to do so, after which you will dispose of it as you see fit. so long as you give them a reasonable period of time that's fine. Pointy out as well that you are not a customer, and if someone is using your name and address it is not you, and JD are being defrauded.
2) Do a credit check upon yourself, check no one is taking out loans or cards in your name. Clearscore is a free app and good enough for these purposes. If someone has then you are not a victim - you have suffered no loss...yet - but it can cause serious headaches and issues further down the line, so worth checking soonest.
3) If anyone knocks at our door claiming a package has been delivered there in error then do not let them have it. Probably best to deny even receiving it. Obviously, if it's a courier sent by the selling company then that's different.
