Cox service is making me lose my hair!!!

I've been dealing with bad internet for 2 months now like 10 tech visits  and  I don't know how many maintenance crews that they claim went out and did something. Its only gotten worse. I also have their "Gigablast" internet which is anything but fast. They've supposedly sent maintenance crews out to look at nodes and the main line.

I've had them try to blame it on me but I've  removed every possible  variable that could be me so that they can't keep making excuses. I use an ethernet cable wired directly to the modem. I'm using their modem which has been replaced by them for a new one. The wire from the box goes two feet  through a wall and directly connects  to the modem. No splitters. No possible bad house wiring etc. I have tried multiple different devices so they can't blame my computer.

I depend on my internet for work and I can barely do my job because the internet is so bad. My work is probably going to fire me at this point. That would make a great commercial. Thanks to cox's gigablast internet I lost my job! Thanks Cox Cable!!
