Going to test this out with a cheap item (£50) and see the outcome  

Update - I used the wrong item received method, just to be safe since the account has no previous purchases and bare bones in terms of personal data. It only contains a fake name and everything else is anonymous.

At first they responded with, send pictures of the item you received and then we can take it further. I didn’t actually have the substitute item with me (not delivered yet) so I just convinced them that I wasn’t home and would have to send the picture when I get back.

I tried my luck again 12hours later and they basically told me they will be starting an investigation with the courier and will get back to me in 48hours. Not sure what they could possibly be looking for there but will update once I get the results.

Update - Once investigation was over, they requested that I add a payment method to the account and return the wrong item.

I have now done so and to continue with the claim I have to sign an affidavit. I have tried to convince various reps to issue a refund but it always ends up going to the internal team who obviously can see that an affidavit form has been requested. As @mothered has stated, it’s legally binding so I don’t want to go there.

I have decided to cut my losses and move on.

However just for future reference.
Considering my scenario, as I am using a false identity, would signing an affidavit with the false information, just to move on with the claim work? Like the account has no information leading back to me, so what’s the worst that can happen? Any thoughts?
