Take it back to em and say " What the F#ck is goin on with this you bunch of C#nts!!!"
Usually gets the point across. I got my stereo installed ans when I got it back the lights on my climate control didn't work. There sometimes pretty rough.
That sounds like a pretty stupid way of doing it.
Would love the fast and the furious look though, at the start of a run down the plex. Would look f#ckin sweet.
