Wish I could give 0 stars!!! Schedule appointment...

Wish I could give 0 stars!!! Schedule appointment to get estimate on replacing my 20+ year old roof. The person sent was a NO show. The person was to call me right before getting to my house so I could meet them (I am working 3 minutes away). I left where I was working early not to miss them. Was at home 10 minutes before schedule appointment time. The person never called and did not show up. I waited over an hour, just incase he was running a little late. I did not even get a call from this companies office to apologize and possible reschedule, but noting, This is not very professional, not calling and not showing up. Is this how this company works?
