Backflow Guy

Terrible service.. Called initially and he was able to come to my house the same day which was great and was told he will leave the paper work so I can send to city which I said fine. When I called back later to see if the job was done he said he will send the paperwork next day, which was different from the initial call. When questioning him about it, he became extremely defensive, hostile, and verbally abusive and instead of doing his job, he told me "I will rip up the contract" and threatening my well being if I ever called back. I was left stunned after he hung up the phone because I never been treated so rudely for asking a question. Please stay away from this guy, Richard...
