Aspen Dental

I have been having dental work done for 2 yrs now sent to 2 different offices. I have insurance and seem to still be paying outrageous amounts i'm up 7, 000$ i've been interest charges threw their dental first plan on teeth that I do not even have.. I've have 4 different sets of partials made and each partial was adio poorly fit that it broke and damaged other teeth causing more pain and in the end more costly dental work.. Today when I questioned these matters they told me they felt we needed to part ways.. 2 more broken teeth and tooth ache from wearing their partial that was not made properly and they say let's part ways?!
