How can one get a conforming ipv6/64 address assigned to ones network?

I was able to successfully pull a ipv6 address , concurrently with a ipv4, as stated in the previous marketing  'a dual stack' the connectivity works acceptably, with more dropped ipv6 packets than ipv4.

Here is the Problem, the address pulled was a x.x.x.x.x.x.x.x/128 'a subnet for a point to point link'  the standards body for ipv6 deployment calls for a /64 subnet to every device.. I would be happy with only a single /64 subnet for my whole network which would let me eliminate NAT.

I called into support and was escalated to level 2.  the level 2 rep, both of them.. were courteous, but could not answer why I was not being assigned a ipv6/64 address. both also were unable to refer me to another branch of the company 'because of some corporate policy most likely'. So i came here.

To reiterate, how can i get a conforming ipv6/64 address assigned to my network? If I cannot why is ipv6 now being marketed as available when only a subset of ipv6 features are instead.

I would be grateful to any person who could answer my questions, or point me to the correct person or department that I might speak with about this. Im perfectly happy going with snail mail correspondence on this issue as well. thanks
