I was in Costco and saw the Collins booth and decided to get a quote since my current unit is over 12 years old. They called to schedule an appointment and one was made for the next day between 11-12. I made sure I was there at 10:30 and stayed until just after 12, but nobody called or came to my house, so I left to finish up my errands. I got a call about a half hour later from Collins saying the guy was at my house. I said the appointment was for between 11-12, not 12:30. I had already wasted an hour and a half of my time and was not happy about not even getting a courtesy call to say they were running late. I was asked if I'd like to reschedule, but that wasn't going to happen. I'd be very wary of a company that treats potential customers like their time does not matter. My time DOES matter and I will be taking my business elsewhere.
