They asked the receptionist if they could leave without being billed, and the receptionist said yes. They went to a different ER as result.3 weeks later they receive the bill for this hospital that didnt give the any service. They called them and they refuse to get rid of the charges and are now threatening to send it to collections.What should my coworkers next action be?  <response>: Ask them for an itemized list of billings and proof that they signedchecked in with the receptionist. If theres no proof they were there, how can they be billed?
