Trying to double charge - 2 paddles on each arm it was double the cost

I decided to use Coeur D Alene Plastic Surgery for my Cool Sculpting procedure of my upper arms. They were very professional from the beginning. I went in for my appointment at 1:00 pm Thursday afternoon and the procedure lasted until approximately 2 hours and 20 minutes 70 minutes on each arm which was the time they allowed for it from the beginning. I thought everything was going well. Everything went if without a hitch.

Here is where the problem comes in. I paid 750.00 at my consultation and was told the other 750.00 would be charged at the time of the procedure. This is exactly what happened.

I went to work this morning thinking everything was great. Coeur D Alene Plastic Surgery called me at approximately 9:30 this morning to inform me there was a problem with the charge to my card. I assumed the charge hadn’t gone through but then she informed me that since they had used 2 paddles on each arm it was double the cost and I owed them another 1500.00! I explained to her that I was not informed of this added charge at the time of the procedure. If I was I would NOT HAVE HAD IT DONE. I’m not sure where to go from here. I’m still very disappointed and confused frustrated!!!
