Generally speaking, I agree that making QoS features work consistently on an external network you do not control is a fool's errand.
But if that language was inserted into the contracts, and you can demonstrably prove it's not being done, enforcing contract terms should always be done. Depending on the strength of the remedy, could have been a lot of free service, enough financial incentive for them to MAKE it work correctly, or leverage to open renegotiations for more favorable terms for you.
You know that in reverse they would have done the same to you. :)
In previous life working with L3 MPLS VPN with deliveries far exceeding on-net size we bought access from partners and had QoS contracts in place, which were tested and enforced and they worked after some ironing during field trials. Usually contract was bidirectional, with partner also using our network for extending reach of their network, so both had incentive to offer working QoS with network-edge translation of marking. -- ++ytti
