Just bought my first item on Vinted and the seller has messaged me that they have sent the wrong item by mistake. They have offered to send me the correct item and said I can keep the current one. I am sure they are being genuine but just not sure what is the best thing to do about the current item which has been delivered to InPost locker and I have not collected yet. I don't want to collect and funds to be released like all is well when I have not got the item I ordered
