Definitely reject and let AliExpress decide. It can’t work out worse for you.
Have you purchased a lot off AliExpress in the past? If you have, they can look back at your history and that should help your case if this has never happened before. I always make sure I mark items received when they arrive etc. So if the worst happens they can see I’ve got a good history.
I got $85 refunded from the case I mentioned that happened to me. The seller was shonky and charged me extra for things that were listed as being included, then a part was incorrect (their fault) and they wouldn’t send the replacement until I paid US$1 in freight. Plus the original item arrived damaged from their poor packaging- the metal chassis was bent. I chased it up with DHL who said the seller would need to lodge a claim for compensation- the seller refused to do it. I could repair item, but they wouldn’t give me approval to disassemble the modules to straighten the chassis. It was nightmare.
