Best Point-of-Use System Installation in Phoenix AZ

I called All Pro and arranged for a quote. They came out and looked at the project, measured, and said that they would email me a quote later that day. This was on Friday the 31st of May. The following Monday I had not heard from them or received a quote. I sent a text message Monday evening to the person who gave the quote and he responded (cut and paste from text) Sorry for the delay, I haven't forgotten- I wasn't in the office over the weekend and I'm just getting caught up. I will have it to you first thing tomorrow morning. I responded no worries--thank you. I am writing this review a week later on Saturday June 8th and I did not receive a quote or ever hear back. How do companies like this stay in business? And if this is what they consider customer service before a sale, imagine the service once they have your money?! Proceed with caution with this outfit.
