<prompt> Human: November of 2017 I got a new job with good insurance. I make an appointment for December that same year to fix my teeth to use up the insurance I have for that year.I go there just for a cleaning but they say I have great insurance and I should use it so I can get the most out of it next year. I ask how much I will have to pay. They say 500 dollars. I just got a bill in the mail saying I have a balance overdue of just short of 2 grand.Im fucking livid. They fucked me.EDIT: To Clarify, I went in for a cleaning but because they said I should make the most out of my insurance I should get most of my teeth filled and cavitys fixed. I also got a crown. I spent 4 hours in the chair that day.  <response>: Have you tried calling them? Maybe it was a clerical error. Never attribute to malice that which is adequately explained by stupidity.
