Best Salt Water System Installation in Phoenix AZ

I have experienced a frustrating poor response and reliability of scheduled appointments.  Multiple times I was assured of a call back "later in the day" to schedule a requested removal of panels to facilitate a roof repair. On the forth day of calling  this company I finally was connected with a scheduling representative... appointment established & confirmed.. no show.. called back requested speaking to someone senior (other than receptionist) waited 55 minutes.. never did speak to requested supervisor ... incrediability poor customer service...
