Seller didn’t send out bundle I payed £50+ for

Yes I got refunded so I’m not worried about that it’s just annoying that they didn’t send it out because I’ve been looking for these books for a while and they’re too expensive for me to buy from places like Amazon for the retail price since they’re academic, and I know that people have lives outside of Vinted, but I just really wanted these books and they had ages to send them off 🥲
