Husband had infection in knee replacement. Hospitalized a week, sent home with picc line for antibiotics. One week later, One Call Care called & said the infectious doctor ordered him back in hospital & a room was waiting, so I drove over 100 miles there, sat in ER over 8 hours and was sent home with no treatment. We are supposed to be paid mileage, but after YEARS of requests for mileage paperwork, we are unable to get in touch with a real person and email gets a response but no real resolution. We are only asking for a piece of paper to send in for mileage!
