Internet Constantly Dropping

I have had issues since February of my internet constantly dropping all the comcast techs say is that my modem is bad. Well guess what I have bought multiple modems and still have the same issue. Now it has gotten so bad I am lucky if I stay online for 15 minutes at a time. I'm tired of calling customer service to be told "your modem is bad" when its actually a line issue. How do I get any actual help? It is hard to pay for a service I am not receiving.

 

Below is the event log from my modem if that helps:
