Good luck. Charter hijacked my prefixes once while I was a paying 
customer (did not withdraw after I shut down BGP) and they wouldn't do 
anything about it outside of wanting to schedule a maintenance window.

But do let us know what prefixes they are so those of us who are 
proactive about such things can filter and do contact everyone Charter 
peers with or where they use an upstream. I got faster responses that 
way than with Charter directly.
