Dentist referred me to Dr. Carnes. Office quoted one amount, charged another amount (over twice as much.) Tried to contact billing multiple times, but I guess that lady doesn't get paid to return calls. She only works a couple hours a week. So, I was sent to collections. Classy. Do NOT trust the quote you're given on the phone. Oh, and I'm having pain in that tooth again, so I'm guessing the root canal didn't work.
