San Francisco, CA
I went to Dr. Tran at Van Ness dental group. She recommended a deep cleaning of my teeth. I agreed but asked them not to use $300 of "anti-bacterial rinse" as it was not covered by my insurance. She did it anyway without making it clear that that was what she was doing, and afterwards (when I got pissed) agreed to charge me only $150. Still paying for a service I did not want, but fine...
She then insisted on a one-month follow-up that also would not be covered by my insurance and would cost $125. I said I did not want this and would just return in 6 months for my regular appointment. She gives me the "one month evaluation" from my last visit six months ago (ABOUT FIVE MINUTES OF POKING MY MOUTH) and charges me an extra $95.
I find out afterwards, am livid, pay her, and vow never to return.
