Basically I'm a bit of an ebay novice, but up until now I've not had any problems. However on Thursday evening I brought a bike from a private seller on a buy now offer. I paid for it on paypal, and I got an email from the seller thanking me for buying it and confirming it was for collection only (it was advised as free P&P but I realise this was an error). I emailed back saying collection was fine and asking for contact details. Since then I have heard absolutely nothing (despite emailing them once more last night again asking for contact details).How long can I reasonably give them to get in touch before I give up and try and get my money back? I really do want the bike, but I don't want to be messed around. Advice please!!!
