Nighthawk X4S C7800 not supported by Spectrum?

It is even more dismal...  Both Spectrum and Netgear have dropped the ball on me, I have been suffering since the middle of September (OVER ONE MONTH)...

- In Feburary 2020 I bought a C7800

- it activated just fine and worked without issue until the middle of September

- in the middle of September the modem started dropping every ~ four hours, a power reset gets me another four hours, I have been trying to work from home in this crippled mode FOR OVER A MONTH!

- I first guessed that the modem was bad, Netgear FORCED me to by a tech support contract in order to get their help, even tho I told them I was just trying to collect on their one year warranty, they assured me that the problem would be solved in 10 - 15 mins if I talked with the tech support folks; something about 3rd party wifi interference... 

- Well it wasn't 3rd party wifi interference and a couple of other router setting changes didn't work...   Netgear finally sent me a replacement (IT IS REFURBISHED)

- Center stage for Spectrum, CLOWNS: the replacement (same exact model) cannot be activated, after 4 or 5 calls I was finally put in touch with someone (at Spectrum) that took pity on me  BUt that was 5 days ago...

- The C7800 was moved from the min supported list to the 1G list

- Spectrum also cannot activete the new C7800 but my first C7800 keeps limping in the "reset every four hours" mode

- Spectrum of course was quick to offer me one of their modems, I declined and asked that they iron out the C7800 support, if yes then please activate my replacement C7800 or REMOVE the C7800 from the 1G list....   I am still waiting for a call back (the Spectrum person that took pity on me had to get supervisor approval in order to promise me a callback, again that was 4 - 5 days ago).

I will update once I make progress.
