Car has to be fixed again

So I got the car back on Thursday of last week. It was late on Thursday. I got there right at 6:00PM when the closed... so I was kinda in a rush. Anyway... the dude there was dumb as rocks... he let me look it over and it looked fine. I tried to open the trunk with the key and it didn't work... so he said "Um... yeah, they said it didn't work in the trunk". It worked BEFORE I brought it here.... so he took the key and looked at it and it was tweaked... so he straigtened it out a bit....
Works now. Took the car home... didn't really notice while I was at the place but the door "dings" like the keys are in the ignition or that the lights are on... even when they are not.
Not a good thing considering that I only have one key for right now.
Anyway... took it back this AM... unfortunately the same bag of rocks took the case.... I get there and he asked what the problem is... so I walk him out to the car and open the door to let him hear the "dinging"... he states "So it didn't do that before?".... um..... no!?! When did you ever buy a car that did that?????!? Anyway... I left it in his stupid hands....
So I called him about 2 hours ago to find out what was going on.... he calls me back and says that they need to replace the ignition switch again... which means no car again for awhile... again I ask... what god did I piss off?
