I tried Ambassador Services for some AC work and walked away with mixed impression. Customer service was good in setting up appointment and worker arrived on time. However, when I called back to get some clarification on the HOURLY rate I was charged, the lady promised to have someone call me back but no one ever did. Yet she did call back later to follow-up on whether I wanted the additional work done with no reference to my earlier concern. I felt like it was all about the bottom-line.
