putting the phone down on someone is rude as hell anyway Id be furious at that, and Id march in and go schiz with them. to pay £30 too for a crap job go in and say that you're angry because your little brother / sister tried to brake and it didn't work and they fell off a curb. Simple enough story (you could say they got mowed down by a juggernaught but you wouldn't really be in the mood for polite words with the shop) really don't take it lying down, DO SOMETHING ABOUT IT!!
