how did you send payment? As you say you bought it? or have you not paid yet?

Also do you have a link or can you explain was it blantantly your fault?

if you don't pay in 7 days he can issue unpaid reminder, then after you reply, or after a further 7 days he can issue a strike. Unless you have had these before then i'd just take a strike ( you need 3 to get banned then you can reopen your account after sending a letter saying sorry). If might not even sleave neg feedback as your bound to give him it back. i never leave a neg i just do unpaid dispute. Whats yourr feedback score like at the mo?

Also you can pull his contact info up if you want to call him? heres the link http://search.ebay.co.uk/_W0QQtZvbQQsofindtypeZ9
