I work in a medical building that receives patients transported by provide a ride on a regular. The company has a driver that dropped a patient off at the wrong office. My office manager and the patient told the driver he did not have an appointment here. The driver walked out the door. I opened the door yelled down the hall to the driver asking him to come back. The driver DID NOT look back, he threw his hand in the air and said I heard her, but did not return for the patient. I returned to the office to file a verbal complaint with customer service (although I feel nothing will be done about it) and to request a pick up for the patient. The diver was very rude and that is not safe for someone to just be dropped off like.
