Fucking Quest Diagnostics. They really took over.

About 8 years ago, one of the Vegas branches couldn't bill my insurance correctly no matter how many times they tried. They kept sending me incorrect bills claiming I owed $95, when I didn't owe anywhere near that. I probably owed like $20 or something. I kept calling them back telling them that they fucked up, and they would resubmit it and just fuck it up again.

After about 6 months and several tries, I stopped hearing from them, but my insurance still hadn't processed a correct claim. I called Quest and asked WTF was going on, and they told me they just zeroed out my account because they couldn't figure out how to bill it.
