Scheduled an appointment days ahead for my 80+ year old mother who was selling her property. She had to drive an hour to meet with them and 15 minutes after the appointment they called her to say that they (1800gotjunk) could not make it and wanted to reschedule for a few days later. She was already there to meet them and was not going to make a second trip.
Do yourself a big favour find a local independent business. They will appreciate when you call them.
