Problem with IPv6

I am trying to get IPv6 working.  Comcast said that I was assigned "2603:xxx:yyy:zzz::/56".  I have a router/firewall connected directly to Comcast's modem which splits it into 3  VLANs.  Everything I read online says that I should use DHCPv6 on my router's WAN interface with a "prefix delegation size" of 56.  And to set the "IPv6 Configuration Type" to "tracking".  No matter what I do, I do not see any "2603:xxx"yyy:zzz:;/56" anywhere.  What I see on the Comcast modem is:

Internet: Active
WAN IP Address (IPv6): [Edited: "Personal Information"]
WAN Default Gateway Address (IPv6): [Edited: "Personal Information"]
Delegated prefix (IPv6): [Edited: "Personal Information"]
WAN Link Local Address (IPv6): [Edited: "Personal Information"]
What am I doing wrong?

I asked for delegated IPv6 addresses 2 months ago.  Since then, several tickets have been opened and closed.  Many without me getting any notification of their status change.  I received an email last month from a tech saying the they thought the problem was corrected.  I replied that it wasn't.  My account is not showing any IPv6 delegated prefix.  I also left 2 voice messages.  The tech never responded and closed the ticket. 

What does it take to get this issue resolved?
