[gardenofeden5253]

hi all,

some purchased of my eBay account, there was messages back and forward more photos sent all questions answer, he sent an offer i accepted. then 24hrs later he wanted to cancel for no genuine reason. i refuse the cancellation order and sent a payment reminder. 

how do i hold him to his commitment to buy ???
