Thanks for your answers but, I click the button 'have you made phone contact' and that allowed me to submit the dispute.
After 4 emails and getting nowhere, I don't think me ringing would achieve anything. I actually wrote to another buyer of his and he kindly wrote back and said after 7 emails to this guy he got no answers, so he rang him twice and each time he hung up when he found out who he was. I've bought off this guy 4 times b4 that I can find and now he wants to go through all this for a paltry $16. Makes no sense at all to me.
