Cox throttling upload speed to twitch.tv

Im an affliated twitch streamer and its really hard for me to do my hobby/job, because of cox throttling my speeds. Already replaced the coaxial cable making sure there are no bends or damage. My upload speed is supposed to be 10mbps, but its very incosistent. The same problems keeps happening for the past 5 months. I drop frames streaming and the stream is never smooth, just as i was growing. I've already had a Tech out and they resolved the problem for 1 day. Not looking to have another tech out.

A lot of other streamers have had problems with cox streaming on twitch. The only conclusion i have is Cox throttling my upload speed.
