I have sold an item to somebody, they are not happy with it despite me knowing there is nothing wrong with the item I have agreed to issue a refund as a goodwill gesture. However I'm fairly new to Vinted and I've never had any issues like this before. How do they return the item – as in do I just provide my address? Once I have received the item back how do I issue a refund? Very grateful if anyone can help me! Thanks in advance
