Ordered my daughter a new hoodie on Vinted. It was a brand I'd never heard of. After a few days I tried to check the tracking information but couldn't. A 'Something went wrong/no content found' message came up. Same when I tried to access the item and transaction. I messaged the seller and enquired as to the item's whereabouts. He said it was on his way. I then saw, through clicking on his profile, that he had been blocked from the app. Thinking that this was all very suss, I contacted Vinted who refunded me IMMEDIATELY without quibble. This never usually happens. I then received a message from the seller asking if I'd cancelled. How he's able to message me on the platform when blocked is anyone's guess 
What I should have done at that point is to block him. However a couple of days later, the item did indeed arrive. I'm thinking it's probably a fake. I've just heard from him asking me to let Vinted know when it arrives, as otherwise he stands to lose a lot of money. He claims that he isn't blocked but is simply loading some new material (so going through some sort of review, I don't know?).
I feel slightly uneasy as this guy knows my name and address.
What to do? Block him (a nagging feeling is telling me 'but what if he's genuine and you're ripping him off?') or delete my account and start another?
Looking closer at this particular brand on Vinted, there does seem to be a few dodgy accounts selling it on there. No reviews, nonsense usernames, exact same postage cost across several accounts, etc. I had picked my seller because he had 20+ positive reviews.
Advice please?
