A+ Tender Dental Care

After joining [redacted] (A Dicount Dental Plan) I Made a appointment with A+Tender Dental Care for a new patient visit for a oral evaluation,Full Mouth X-Ray and Prophylaxis around September,25th 2012. A+ Tender Dental Care was a participant in the plan at that time.On October 2nd I went to my appointment and discuss the cost and the free Semi-Annual Prophylaxis. After my appointment on October 2nd I paid my bill and then I ask for an appointment for my 2nd Prophylaxis. And they told me after January 1st 2013 they will not be honoring [redacted]. I felt I should has been told this before my appointment.So I could have the option to cancel the appointment and gone somewhere eles.
