Centurylink SOC contact?

Does anyone have a contact for the SOC at centurylink? I've tried soc@centurylink and noc@centurylink, with no answer.

For whatever reason, they're mangling IP address in abuse reports, which requires us to manually review every report. We'd really like them to stop, and just include the IP address in the body of the report.

They seem to be the only ones that do this, pretty much all the other reports we get list a normal IP address.

I responded off list.
