A long story short, my dental office sent a bill of mine that I was unaware of to collections back in February of this year (supposedly, as I have yet to receive any notification or letters from said collector). It was a remaining balance of a surgery I had that I was told my dual dental insurance would cover and that I would only pay a portion which i had thought I paid. And I never received a explicit bill, just 2 really vague bills that had no due dates. And they were never able to give me clear answers for what exactly I owed. There’s more to that but…

Anyways, today I tried calling to schedule a cleaning as I still have insurance and it is covered with my insurance as I’m due for a cleaning and will be getting my braces off. They before even asking to identify myself over the phone put me a hold and told me they are unable to schedule me due to my account being sent to collections for that past due balance. I asked how I should pay it since I didn’t know they could refuse me services as they also have not sent me any letters terminating me from their practice due to this. They then proceeded to give me two phone numbers that don’t lead of anything. And did not give me the name of said debt collector. What are my rights here?
