Although Dr. Hill seems to be a good dentist his practice is off to a bad start.His staff for billing purposes consists of one woman who is the worst at customer service that I have ever seen.I went to this dentist because of location and a coupon that advertised $50 off any dental procedure or treatment. I made initial appt. and provided my dental ins. info.I was told I needed to have 8 cavaties redone because of shoddy work by previous dentist that I was unaware of.I made 2nd appt for the upper left quadrant and was worried about cost because he uses resin which is more expensive.After he did 2 fillings I was charged $215.00 for a bill that was $324.My statement showed that I had a $50 credit from the coupon.I asked if that was correct with insurance and the lady said yes.It turns out that ins. paid them $219.20 and when I called to ask why I was overcharged and to ask for my $ to be credited back I was put on hold and told that they would only credit back $110 which would not include my $50 credit.So this lady has the audacity to overcharge me by more that $100 and then refuse to use my coupon because I wanted the overcharge to be refunded.Very shady considering that she knew how worried I was about cost.
