Xb10 Availability and Mid Splits

For the last three weeks I have suffering slow speeds interrupted service etc. I work from home hence I have the Gig speed and it has been slowing to a crawl which in turn affects my job. I understand by driving around that they are prepping our area to compete with the new Fiber Optic network Lumen technologies recently activated as I have seen one of the big white nodes. down the road. So, it is obvious. I went to my locally owned Xfinity store and the kid there was talking about an XB7 combo and had no clue about the existence of an XB10. So, I called and spoke to one of the people in the Philippines who earns $10 a day at a call center, and they were completely lost. As I also had a problem with my Storm Ready Wi-Fi which has never really worked, and I was told to take it to a store where I had been, and they told me to call!! So what gives on the XB10 upgrades and the Mid splits as I have equipment which supports WIFI 7 as does lumen so what gives Comcast? So, with customer support like that who needs enemies attacking the networks as Xfinity is sinking it themselves.
