Verizon MPLS service in Anchorage

Hello, I've got a bunch of sites connected to the Verizon Private IP MPLS service, and recently brought online a location in Anchorage connected to the brand-new PE node in the same city. I'm seeing that packets marked as DSCP EF are given fantastic treatment (low jitter, no packet loss), but other packets, including AF41, AF31, and BE are given what appears to be the "junk bucket" treatment. I'm having a difficult time getting anyone to acknowledge this problem, but it's causing interactive applications to be unusable for times of the day. Can anyone point me in a good direction? thanks.
