Don’t you don’t care for it when you call for some kind of service and they do not show up within the scheduled time frame? I know I do! This happened on our last Heating, Ventilation plus A/C service appointment from our local heating and a/c corporation, and usually these people were always either on time or occasionally a little early. Which depending on the time scheduled, being early can occasionally be a good thing! Better early than late is how I see it in our book! But this last heating and a/c service appointment was beyond the term late! They ended up not showing up at all! I had to have the whole appointment of the tune up of our central heating and a/c program rescheduled to the really next afternoon and do it all again with the super long time window; They ended up calling myself and others a half fourth after the time window ended telling myself and others they were sorry about not showing up however they got tied up on another heating and a/c service appointment that was before mine. While this is understandable, that is still no excuse! They could have called earlier if they did not have a back up plan, or, they could have just dispatched their emergency heating and a/c service service people free of charge since i blew our whole entire afternoon waiting on them! When they wanted to reschedule, I told them no and that I was taking our corporation elsewhere. That was not a really professional transfer on their part, and it cost them an otherwise loyal customer!
