Cancelled and refunded order delivered weeks later

AlanRD

So, as the title says, a few hours ago today, an order from Amazon that was cancelled and refunded a few weeks ago was delivered.

Before I go on, I apologise for this massive wall of text. I just want to get all of the details straight and laid out.

Here's the full situation: I ordered two parts on Amazon to replace one failing part in my computer. One for ~£55, the other for ~£111. I needed them fairly quickly, so I used my prime next day delivery. Soon after I placed the order, I spotted the £55 part on Amazon Prime Now (the same-day delivery service), and realised I could get it within an hour, and I really did need to rather quickly. So I cancelled the £55 item from the order, and it was removed successfully. I was only charged £111 as I should have been, but this point will come in relevant later. This was on the 5th of January.

The £55 part came the same day, but the £111 part didn't come the next day (the 6th). Nor did it come on the 7th, so I contacted them on the 8th asking what was up. The support agent did their thing and contacted the courier, promising it would be delivered within 24 hours.

Of course, it wasn't, and I noticed something odd about my bank account. My available balance was far lower than it should have been, and after phoning my bank, it turned out to be because Amazon had a hold on some money from my account for the full £55 + £111, despite me being separately charged only £111 for the one part that was shipped, and the £55 for the part from Amazon Prime now, both separate to this £55 + £111 hold.

I contacted Amazon to check the status of the order, and about the hold on my bank account (which was on hold until the 19th, the date at the time being the 9th). They gave me the settlement verification code I might need to make my bank release the hold, and all went well on that front. Again, though, they promised the item would be delivered within 24 hours.

I gave it a further 24 hours, and on the 10th, contact them again when it didn't arrive. It turns out it had gotten lost in shipping (as I had suspected). So, they cancelled the £111 item, and I ordered another, identical part from Amazon with pre-12pm delivery (that they waived the cost of). Sure enough, that item came the next day at something like 7am. Nice and early!

So now, we get to the meat of the problem. Today, the original and lost £111 part was delivered by Amazon. I noticed the email saying it would be delivered today, and told myself I would simply reject the parcel at the door, since it had been cancelled. Unfortunately, I couldn't do that, because they simply shoved it through the letterbox.

My question is this: this wouldn't be considered an unsolicited item, would it? Would I be legally required to contact them, and let them know of the mistake?

Thanks a WHOLE bunch to anyone who got through that wall of text!

Sui_Generis

The answer is a simple one, through whatever process you've received something you haven't paid for and thus it's not yours. Go to Amazon CS and get them to call you back (very efficient IME) and arrange for them to send you a return label.

Why run the risk of being pursued in a few months for payment for something you wouldn't purchase and presumably don't want now? As you've stated - you would have rejected it at the door.
