Report
Had an appointment today to fix our Fujitsu Mini Splits. Waited almost two weeks without air conditioning for this appointment. When no one showed up was told they no longer service our area. No cancellation, no warning, no nothing - just didn't show up. Now I find out there is no Fujitsu dealer that services this area and I'm stuck with $9,000 worth of air conditioning that doesn't work.
