I was given a service window of between 4 p.m and 8 p.m. the service guy shows up at 10:30 p.m. not a problem I needed the service.

Now where the problem comes in is that he left without giving me a quote or anything written.

He went in the back yard looked at my unit and JUST GOT IN HIS TRUCK AND DROVE OFF WITHOUT A WORD!!! WHAT TYPE OF BUSINESS REP IS THIS?

Also I was informed that Humphrey Guardiola would be the tech, this guy introduced himself as Frank! I'm feeling really disturbed by his unprofessional behavior. I waited hours for this non-sense!!
