At minimum I'd say animal cruelty, but before you act, calm your emotions, or work with someone who is calm. My mom was very fond of the phrase "you catch more flies with honey that you do ****." I think I speak for most the forum, we will be behind you through all of it.

This is really sad. Like I told you on FB, in my office even when the patient owes money we still see them if they have an emergency. It's not about the money, it's about making them feel better. I also think (at least in dentistry) it is illegal for us not to see someone that has a problem if they owe money. Once we start a treatment on someone and a problem arrises because of the treatment we have to take care of them regardless. Also, you said they didn't treat her with antibiotics after her surgery because their office is sterile? That's not why you use antibiotics you use them to treat the inside of the body not the outside. If you only use antibiotics because you are in a dirty environment, then the whole world would be on antibiotics!
