really

So a few days ago my central vacuum system in the house quit working. So i tried to check for blockage and nothing. So i called for a service man to come out and check it out. So they were suppose to be here at 130pm and didn't show up till 2pm grrrr. I hate when i make an appointment for something and they cant be on time. So the guy comes in checks the vents all okay, goes to the garage and notices that the people before decided to move the unit in the garage and do their own pvc piping work and it was all lose and not fitting. He opened up one of the connectors and there was a AA battery stuck in it along with a ton of back dirt. So gross. Now it is clear and working great.

What will I find next that they half assed?
