I called and set up an appointment we waited about a week. I took off work to be at the appointment but they never showed up. I called to find out where they were at and why they missed our appointment and they had no idea what I was talking about. When the lady called back she said oh your appointment is next week. I don t have time for companies that set appointments and don t show up. Then want to act like I made a mistake on the dates.
