i don't see theres anything wrong in whats been said, after all the guy used the site to obtain money and business, i have read a few posts regarding this problem and its still not yet sorted out. he has had enough opportunitie surely to have this matter resolved so why not let pingu stress his concerns on the site?
Its the same as when a canvassing company doesn't deliver or rips someone off...they use the site to obtain business...people then have the right to voice there opinion if it all falls through to put out the warning signs for everyone else to see. Then they can make there own mind up about dealing with this person or company again.
If you run a straight business you wouldn't of had this type of problem to start with. As for naming addresses so what? if it was a legit business we could quite easliy look up the contact details anyway
just thought i'd add my thoughts on the matter after reading the post.
