Dr. Farid Noie (Unicare Dental) No refund, long wait time Webster Texas

I have had appointments (yes, more than one) run approximately 4 hours, with actual interaction time being 15-30 minutes. I am one of many this office inconveniences, as I have witnessed others wait or leave in frustration over the wait time.
I was talked into getting a Care Credit card here, which I now need to cancel, and I'm sure will affect my credit score. Hardly anyone accepts this card, and the interest rate is crazy. They are currently hassling another doctor of mine.
I had a filling fall out 2 weeks or less time after I got it put in. I was given incorrect information regarding my filling options, as well. The other opinion I got was that the treatment he highly recommended to me was far too extreme. Thank goodness I went the "cheap" route, according to Dr. Noie.
Obviously, after all these terrible experiences, I went to another office to get my work re-done. I called their office BEFORE I got the new filling asking to be refunded for ONE of my three fillings. Only the one that fell out. I find this to be a reasonable request. Because Dr. Noie speaks to me like a used car salesman, I also asked I not have to speak with him, as I had already made my decision to go to another dentist, and did not want him trying to talk me in to going back to him. They did not contact me for a while, so I had to get the work re-done before we spoke again.
I received a call today saying Dr. Noie refused to refund me because he "wished I would have gone to him". I explained once again, a little less nicely this time, that I do not trust him to work on me, and that I just need refunded for the sub par work. I was told this was not an option. I paid a total of $627.00 for the 3 fillings, no insurance. This office has now stolen $209.00 from me. I am beyond furious.
