Xbox one , one s, one x, terrible upload starting oct 2019 after maintenance, and now it’s back in oct 2020 after maintenance. Fix this SOON @COX

I live in northwest Arkansas and I’m an Xbox gamer. October 2019, Last year, after cox did maintenance, I talked in person and by phone  with cox and Microsoft for hours/months over my gaming console reading 3 mb/s upload yet I pay for 30mbs upload. Cox blamed Microsoft, and vice versa. I finally gave up. Spring of 2020 cox did maintenance again and my upload was finally back. Now, it’s October of 2020 and cox just did maintenance again, and for the past 2 weeks my console is back to the 3mbs upload or less during prime hours “evening”. I have records of all of this. You guys know what you’re doing @cox. Please stop and Please fix this SOON. Thank you.
