So today I needed a warrant because it was a few months overdue

and I couldnt get Rego without one. I knew I needed new tyres so I got them this morning and I decided to put the car through a WOF place to see what else might need doing for the car to be safe. I already knew the balljoints were rooted and theres quite a large hole in the exhaust and thought the WOF would point out anything else that would need fixing so I wouldnt fix balljoints and exhaust only to fail and have to fix more stuff. I chose a $25 Wof on the go place because I didnt have to book and I was in a major rush.
The warrant took a wee while but most of that time was just the car sitting out the back with its bonnet up (Whats under the bonnet for a WOF?).
Anyway I digress, it passed and nothing was said about the hole in the exhaust but he mentioned the balljoints were worn but within limits. I can't see how they are within limits when the brake pedal shudders under braking and theres massive knocking sounds coming from the front. (I replaced them tonight anyway.)
Do you think I should complain about this?
This is pretty bad service yeah?
