Pinging noise coming from the front right

[hachi-roku_fan]

So my gfs Yaris started to make this pinging noise that comes from the front right wheel well. I took a look to see if anything was loose, everything looked nice and tight. But it still sounds like a metal on metal, hitting the dust shield. I took it in and they gave me some BS that since I didn't buy it there, I would have to go through an inspection, if it turned out that impact related, which it isn't, I would have to pay $99. If its under warranty, they'd take care of it. Has anyone else experienced this type of service? I was even ok with that, and the attendant was like "Oh but we can't do it til the New Year." with a horrible attitude. This was in Hollywood Toyota. I think I'm going to call Corporate. Has anyone had anything like this happen? If so, what was the issue?
