Newest equipment is not worth it

I have the latest and greatest in xfinity equipment.  I was told the only way to not get charged for overages was to go to a new plan and new equipment ( BTW, I was initially lied too as I see you don't have to use your equipment, yes your agent lied and blatantly did it).

It has to be restarted all the time. Kids can't do homework,  wife is a teacher and that frustration is something a husband should never have to go through because your internetwent out, but you DON'T CARE.

Tip of iceberg as it is not 2.4 compatible so nothing on my wifi smart house works and you have no solutions.  I even bought brands YOU SAID would work to replace the ones not on list.

What is wrong with Comcast? Seriously, what is wrong with your company. I see a tin of reviews where you guys are awful not just to me, but to everyone.  

Is it true I can use my own equipment? Was I lied too? Let's start with this one first and we can move on down the list of how you can help a person who pays you [Edited: "Language"] tons of money and has bad experiences and no one to talk too.
