I posted an item on 20th July and it didn't arrive until 1st August.
Seller posted an item on 21st July and I still haven't got it.
The Royal Mail tracking site just says "Your item was posted at xyz [in the UK]. More information will be available as it travels through our network." Vinted says "Your order is still on the way. It can take shipping providers up to 25 business days to deliver orders."
That's no good to me! I'm probably going to be away when it arrives. Anyone else having this problem?
