Unless you are able to show some clear pictures that a layman can understand, they might choose to believe the vendor's story (for all we know, vendor could be telling them that you are trying to scam them).
So, your complaint has to be the cleanest, simplest, and most direct possible.

Yep.
I learned previously that AliExpress loves video evidence so tomorrow some poor soul in China will waste two minutes of his or her life watching me test eight voltage reference chips with a DMM. Roughly ±4mV spread, far out of spec, but I didn't even post the spec, just said it's supposed to be 5V :D
Then the soul will be rewarded for her patience with my beautiful collage. Check it out, it's a work of art :-DD
If this doesn't work then I'm buying an AK47 and a one way ticket to China >:D
Oh, and by the way, I learned that counterfeiting Intersil ICs is actually fair game. Because they have been bought out (by Renesas?) and whoever did it, they didn't bother refreshing the trademark registrations. So they are expired now. IANAL, but I'm no longer convinced that any IP infringement took place, just ordinary fraud. So I didn't even mention it in order to fit more important things in their 500 character limit.

In this case they offered to force the seller to pay the bill. But I would have to save that bill, send it to them, wait for the parcel to arrive, for the seller to confirm, maybe the seller wouldn't be happy that two ICs are cracked to see what's inside, that sort of drama ::)

I don't think two cracked ICs is going to be an issue in this case - OK, give him 25 cents each or something... :D
It is actually not at all legitimate for seller to ask buyer to pay for the disputed goods to be shipped back. Essentially, the legal situation is that the original contract has been broken (by seller), which has resulted in the current situation where seller has some property of his taking up space at the buyer's premises!
It's like if you rented a car, and it then breaks down during the trip - the car is still owned by the rental company and they have to recover it after breaking their contract of providing a working vehicle to you... your only obligation is to park it as safely and responsibly as practically possible before you abandon the car and continue your journey by other means!
According to AE's web site, "We promise your money back if the item you received is not as described, or if your item is not delivered within the Buyer Protection period." Furthermore, it states: "The seller must comply with other relevant legal requirements (warranty, return, etc.) that may be applicable depending on your location as buyer. For instance, in most EU countries you will generally have a 2-year legal conformity warranty.
Thanks to the European Union (European directive 1999/44/EC), for any purchase in store or on the Internet from a professional seller, you benefit from a legal guarantee of conformity of at least 2 years, which allows you to ask the seller to repair or exchange the good, or if this proves impossible, the reimbursement of the sums paid.
Basically, AliExpress and the seller don't have a leg to stand on legally and in principle you could keep annoying them for years by raising new cases for non-conformance for every individual IC on that roll, LOL! :D

Sure enough, I just opened one and it looks like Noopy's pics of REF01 so I guess it's REF02. There is even PMI logo on it, so I may be able to point it out.
I could power them up and nail them on tolerance and power consumption, but I feel like it's futile. However, REF02 sell for absolute peanuts on AliExpress (prolly recycled or fake, but not my problem) so I'm tempted to request the difference between what I paid and the going price of * REF02 and see what happens.

You may want to edit out the racist slur.
What I do from the start, let the seller know: I received this IC, this is what I measured (xV), it does not match the datasheet, show photo of DMM + datasheet, I will have to leave a 1 star review.
A reputable seller will try to work with you.
If you bought from a poorly rated seller then its a lot harder, and not worth the effort IMO. Assuming you spent <$20 on these, if you spent more, then next time do a test purchase before committing to a vendor.

Well, right, it's like I rented a car, it ran a little slow and I started to suspect something may be fishy, so I cut out half of the car to find a lawnmower engine inside, and the owner should just accept the car back as-is 'cause it originally was his fault.
:-DD

Legally, the thinking is always in terms of actual damage caused to the injured party. So, you destroyed a couple of his fake devices - but the devices are literally worthless, resale value zero - so no actual legal damage has actually occurred! Whereas the damage that seller caused to you is completely real - "liberating" the entire purchase price from your wallet under false pretences!
