In the most recent case I tried to get a written quote for procedures because of past problems. I was given the run-around until all I could get was a verbal quote over the phone. But if that wasn't good enough, my only recourse was to delay getting a suspicious lump examined. I was then charged more than I was quoted, and I was even billed for procedures they didn't do. I actually heard one of the employees say "I added that because I thought he was using insurance". Still - hours of phone calls over several weeks before they would even bill me correctly without adding tests that they had no results from. And even then - more expensive than they told me because the person I was transferred to over the phone was in a different state than the clinic I called in the first place.
Absolutely rotten.
