the joys of childrenBuyer won item and now claims 6 year old child made the purchase.Have asked the buyer to request mutual cancellation of the sale but I am a little annoyed to be honest about the whole thing. Sorry just wanted to vent
Its been so long since I have used eBay and I was wondering if someone could please tell me how long you must wait till and after a sale before you can lodge an unpaid item dispute please?Thank you in advance
