Did you pay via paypal, if so start a claim.
i brought this fella to the attention of mods on here before as he has ripped off many people... a member on toc-irl has mentioned that he "did" send the bonnet but if thats the case then why is he ignoring you..?? ill believe it when the bonnet arrives at your door...!! that still wont defend him tho if so as he has ripped off loads of people in ireland...
Sorry to hear this bro,
We have had a few run-ins with this person before. To the extent that they have had an 'Untrusted Seller' tag added to their username(s) so I'm guessing you made arrangements outside of the forum unaware of his rep?
If you used paypal you can raise a complaint via their resolution centre. That should be awarded in your favour if he continues to ignore you or cannot provide proof of shipping. Takes a while to sort unfortunately.
Although if you used a credit card to pay then use the cover on that card to get your money back and let them chase him.
Let us know how you get on,
Jay
