Sold fakes

My kid bought a pair of Jordans from vinted and thanks to r/legitcheck it was obvious they were fake. My son clicked the item had been received then left a 1 star review, so we now can't report a problem. Their support said to message the seller who has goaded my son saying "of course they're fake, what did you expect at that price".

The seller is not willing to offer a refund, so what options do I have other than lodging a chargeback request with the bank (Revolut)?

This is in the UK
