I ordered an item 2 months ago and alerted Vinted after 1 week that I hadn't received it.
Communication was poor and I had to dispute the transaction with the bank who, to their credit, looked into the issue thoroughly. They sent me a papertrail clearly showing my order being delivered to completely the wrong address, including a photo of a stranger signing for it.
It's a clear case of the courier making a mistake. Vinted refuse to refund me or to follow up with the courier (Yodel).
So, if you're ordering from Vinted, bear in mind you may not receive your order or a refund.
