To no avail

Went in for a second appointment. Had labs done two weeks prior to appointment, critical TSH lab took two weeks to get. Only to have and NP tell me that I may have thyroid cancer and she can no longer see me. My thought, if you can’t see me as a patient why bring me in for an appointment to tell me that just tell me on the phone. Now I have a bill for no care that was provided I’ve made three phone calls to discuss this bill to no avail. No one has called me back to discuss this matter with me.
