<prompt> Human: My girlfriend went to urgent care today because her family has a history of blood clots and she had some symptoms of one. urgent care said she needed to go the ER so she did. She waited around, got taken to a room and then nurses said it looked like it could be a blood clot and they took her to get an ultrasound. then the doctor came in, said there was no reason for them to have said there was a blood clot. that it wasnt in the right spot and it was just a pulled muscle. then they told her she had to pay 1300 dollars for it before she could leave. All of this seems very sketchy to me and was wondering if anybody had any advice. Thanks guys!Assistant: also, they didnt give her any sort of invoice or receipt  <response>: Figure out who owns it and contact their corporate office.
