i hate it when things like this happen!
yes i have done it before.... got so annoyed with a person fobbing me off that i gave them both barrels over every internet forum that i could that they would read!
then spoke to them properly and felt a complete idiot for doing it! sometimes it is the only way you feel to get it off your chest but it doesnt solve anything, it just makes it worse for everyone!
every one in a way is allowed freedom of speach etc but shouldnt get involved unless it directly involves them in some way or they have had a similar experiance and say how it was resolved! ie no "what a tosser" comments!
just my 2p worth!
