basically i sold an engine on ebay 2 months ago, chap paid for the engine via paypal arranged to collect and never turned up. i have his mobile number which i spoke to him on to arrange but is not switched off and hes not responded to any of my e mails txts voicemails etc. im just wandering where i stand about reselling it? is there a set time i need to leave it? really need it out of the way!
