<prompt> Human: I booked an appointment through a website zocdoc and their profile said they were in-network for my insurance, when in fact they were not.I found out the hard way when my credit card had hundreds of unexpected dollars on its bill. Is it illegal for them to do that? Is it unreasonable to ask for a refund?  <response>: They can be in network for blue Cross in general, but not in network for your plan specifically.
