Terrible Service

I have now wasted an hour of my life on phone support with someone asking me if my cable is plugged in when I told them the router is losing Sync and an upstream channel is going down more than 5 times a day and an entire day waiting for a service tech to show up.

Then they send a tech out, who spends <30 minutes watching a line and leaves doing nothing since the problem didn't happen during that short time.

And yet my internet continues to disconnect, the same problem I had last year during hot weather, and I have actively cooled my router while plugged directly into the cable line to the house. It isn't me or my modem Cox.
