Then sue MCI for denial of service. You will win in court because it is
trivial to show that the packets came into your network from MCI and that
MCI's employees could not and would not provide any information to you
that would indicate that these packets do not originate from MCI. Thus
they are not providing you the service that they contracted to provide.

Not everything has a technical solution.

Mind you, you might do better to be a bit more diplomatic and take up the
issue with MCI's management. Just keep in mind the basic principle that
MCI is responsible for the DoS traffic unless they are willing to identify
the source as somewhere other than MCI.
