IPv6 dose not come through any longer

I own an ASB8200 Modem that has a 1000 mbps internet plan and I only get ipv4, no ipv6. I use to get ipv6 and ipv4 one day ipv6 drop out and never came back. I already reset the modem and try to directly connect to the modem without my router and still no ipv6 only ipv4.  I try to chat with xfinity but I can't get through. I don't even want to call as I will be on hold for hours. Any suggestions?

Found a solution that works for me after chatting with tech support and waiting for a call back from tear 2 support because tear 1 did not know the difference between protocols. 

 

I found this enabled on my modem:

 

Link Aggregation Configuration

NOTE: Ethernet Link Aggregation applies to various methods of combining (aggregating) multiple network connections in parallel in order to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the links should fail.

 Enable LAG
 
I went and disable link aggregation and modem reboot. I then went and check logs in modem and found the IPV6 protocol enabled successfully. 
I went ahead and reboot my router and here it was IPV6 working again as main protocol and IPV4 as a fallback. 
 
Comcast tech support is so rude and not professional. No knowledge at all bunch of people that has no business working in IT reading answer prompts. I wish that there would be another provider in my area!!!!!

Would like to know of a solution that doesn't require disabling LAG.
