We are basically covering our asses as a public forum. If people ask for the name in PM thats not a problem. U can even say the suburb the shop is in but not the name. Basically the rule is "if u cant say something nice, dont say nothing at all"
I know how i would feel in the same situation and have in the past but unfortunately its still not allowed. SAU does not want to be caught in between unhappy customers and businesses, dodgy or not. This kind of stuff can really affect small business. If there is a problem i suggest u take it up with the dept of consumer affairs, if u think it worth while.
