Best Backflow Testers in Detroit MI

I attempted to call to get a quote. I was directed to the man who would be doing the quote since they said he did his own scheduling. I never heard back after leaving a message and then called the office again; they said it was strange and that he usually returns all calls. They took my information an assured me that they would make sure I was contacted, that never happened and it has been over 2 weeks. It's safe to say that I will never be using Nelson Bros. EDIT: This was a month before any pandemic lockdowns unlike what they are trying to play it off as.
