<prompt> Human: She had x rays done and a neck brace and we were told we had to pay the 600 bill. So my mom wrote a check. That week, the person who hit her had their insurance send the hospital a check for the medical attention. They cashed both checks and now wont answer us or give my mom her 600 back. Every time she calls or anything she gets told they dont know what shes talking about. She even showed them proof that they cashed both checks and they wont talk to her.Assistant: Is their billing team at the hospital on the weekend?Human: Im not sure. I can try calling and asking  <response>: Ask to speak to their legal department and very patiently explain the situation. Do not get angry, just report the facts, dates, check info, etc. and ask if they can help you resolve the problem.
