Don't think Jamo is asleep..
There is a separate area to start Threads of Post regarding suppliers etc. but as this is an Australian issue I feel the Moderators allow a little slack with Threads or Posts that fall within our circumscribe -Australia.
As this is a so called "business" that affects Australians only, it probably fits/falls within the guidelines.
However, if the Thread became abusive or headed in the direction of libel, no doubt the Moderators would close or give appropriate advice on Forum guidelines.
I agree with comments made, that is if this business is selling sub standard or not delivering it should be highlighted and as many as possible made aware of him.
