I had some dental work done at aspen dental October *, ****. and that they told me that the remaining balance of$***.** was wrote off. and the dentist that did the work on my mouth was out of network and I was not informed about that. and after that they did the work they started billing me$***.** and aspen dental is wanting me to pay. that's what I am suppose to have insurance for. and to be honest with trans union and all of the credit companies. they merchants are tell me one thing and doing another . which leads me to the question where is the money that was made to pay these people for their services going and why are they not wanting to pay these people? and want the clients to pay. what kind of business that is ripping the consumers off*
