Will I get my £290?? Buyer suspended after transaction

This buyer purchased a ps5 from me and I was notified that it was delivered successfully. Just before my payment was meant to be released they suspended the transaction. The buyer will not respond to me but is viewing all of my messages. It says that vinted support will contact me but how long will that take?? Will I ever receive my money?? I’m scared because it’s such a large amount and I really need this money. I’m not an experienced seller so I don’t know what to do, please help!!!
