Help with GC/Level3 route issue

Hi,
I'm facing a problem that is becoming a nightmare.
Some of our prefixes (ASN 10277) are being redistributed by Level 3 as
being learned from/originated by Global Crossing.

Thing is, we have no contact with GC nor Level3. I'd appreciate any kind
advice as to who to contact regarding this. Sorry if this is not the
right channel too.

Care to provide some of the prefixes?

Sure, I just was unsure that the post was ok in this forum.

We are advertising 168.83.20.0/23, 168.83.60.0/22, 168.83.68.0/22,
168.83.72.0/21 & 168.83.80.0/20.
(Now we are injecting /24 as a quick hack to patch the situation).

GC is advertising various 168.83.0.0/16 subnets too, which is ok,
but e.g. the 168.83.20.0/23 is there w/o reason.
