Comcast Support

I experienced a loss of Comcast IPv6 service at my home I think it was last Monday... My pfSense reported loss of reachability to the IPv6 gateway, IPv4 still worked but I had a period of intermittent high latency...  Does anyone know if Comcast is monkeying around with their IPv6 network?

I hate to use NANOG for this, but support has now ended a chat with me twice without fixing anything, they just kicked me off.

I'm not getting an IPv6 address on the Comcast provided cable modem/router.  I'm not getting a PD.  My machines thus have no IPv6.  I've hard reset my router 4 times while working with Comcast, and I've been told to do things like switch to a static IPv4 address, which shows a level of clue that is scary.  And before that they were convinced it was a wireless problem even though I have a wired connection, and told them that multiple times.  I've wasted two hours with Comcast today, and even when I asked for escalation I got nothing.  Just hung up on.  It's honestly the worst customer support I've ever received.  I don't think I ever got them to understand the difference between IPv4 and IPv6.
