Non Fiber speeds over 3.1?

I'll preface this with, AT&T has offered to come buy us out on our Cox account / equipment, and install FTTH for us.

But.. we like Cox. For some reason we're loyal. We recently upgraded to Gigablast in Escondido California to get away from the insane datacaps. In our home we have four content creators for Youtube and Twitch.tv. This means we consume a lot of bandwidth, and most of it is outbound. 4-6x pc pushing constantly pushing 60fps 1080p video at a bitrate of ~8k, not to mention constant downloads from gaming and video.

Fine. Super excited to get fiber / gig speeds! But there's a massive catch, that specifically effects people like us, that makes AT&Ts offer so much more alluring. Our speeds are ~950/35. 35???? We were never quoted a speed, but when you are told you're getting 'gig / fiber' speeds, you typically assume (as is common knowledge) that's a 1/1 connection. 1000/1000, not 1000/35. 

This is separate from the fact that our connection has been consistently spotty since we started going in and out, throwing our streams off causing actual financial issues.

I spoke to two reps on the phone who said 'nooo wayy you' should be getting 1000/1000 you need a new modem'. Drive to the store. They tell me there 'yeah 1000/1000' who was the tech that installed your modem?'. I figured it was an error so Cox sends another tech out. He's completely clueless and just does some tests and says 'it just doesn't go past 35 sorry'. He calls his manager on speaker phone who then proceeds to say 'wtf are they doing? 35 up is fast and strong! We never claimed anything otherwise. They have to deal with it'.

Cox... Come on. What a serious let down. We get the most laughable looking connection at 1000/35, and our connection is constantly spotty right around 8pm every night. This is after having two new taps installed mind you, in a brand new development. Brand new homes. 

It all boiled down there not being fiber from the dmarc to the modem. Cox. I want fiber from my demarcation point to my modem, and to get the speeds we need. The Cox contractor said we'd have to hire someone privately to run that fiber line for ~$500. No. Not after having my rates raised for so many years, after having our connections dropped, lost, and tossed around on the phone for hours at a time to have my router reset a million times.

AT&T offered to come handle this for us, and give us the speeds we want, citing Cox's contractor model being the issue with allowing people to do  that work, and even offered to do it free for the rest of the houses in our new development if everyone wanted real fiber.

Cox. Will you come do this for us? From what I know it's a simple job. Can you send someone out to correct this, or are myself, and my HOA switching our neighborhood to AT&T in the next month? Help us stay loyal in the midst of these data caps and rate hikes, do the right thing, run that *** cable and give us the speed we need and will utilize.
