Ok.. a shame if it does contain a disclaimer but if it does you should still be able to get an independent 2nd opinion. This means you should be able to get them to send it to another tester of your choice to check it out. Take a look at the complaints information that rancid Tom has posted... I reckon if you contact there governing body and ask for some advice, then wave the forms above at the bottle testing company, they would be hard pushed to refuse it being sent somewhere else
They "appear" to be throwing the book at you so throw the library back at them!!
