Best Ongoing Maintenance And Service Programs in Phoenix AZ

I called them Early this morning they said they would have some one here between 10am & 12 I waited till 1 pm called them . They said they would have some one call me right back !!! They never called back so I called again they said someone was still coming .

Called them back at 3 pm they said if I could reschedule i no ! They said they would try & get some between 4-6 pm . Then called back a few minutes later to tell me they were coming .I cannot reschedule Because no one will be here on Monday . They basically waited till 3.30 pm to let me know they were not coming . It is Friday to late to reschedule someone else to come . NOT VERY PROFESSIONAL
