Good service and very good staff

My wife Christine Andersen was charged for an extra exam last year that I called the office about. No return call.Then I received a collections notice (email and letter). I responded via email. No response.I myself then went in for a cleaning this week. Before my cleaning and after I was seen, I was asked about it again in a very public forum by 3 separate reps. The unprofessionalism by your staff was on another level. I asked if they wanted to lose my business for $50? Apparently so.
