Internet connection problems for the past two weeks!

I have been having connection problems since I moved in but they were minor and transient. The past two weeks it started with an uptick in instances. The past two days there is simply no connection? I had two techs come out and check the lines. I have two cable modem and router both new. Nothing is working. New cables. Two connections with the same problem. 

I am seriously about to find another isp. 

This is not an isolated issue. They are going to lose a lot of customers if this continues.
