Verizon ( DNS managers out there?

If there's anyone out there who is responsible for the UU.NET nameservers (, can you please contact me off-list?

I have a customer who is trying to move their DNS off of UU.NET and of course everyone they used to know as a technical contact is no longer available. The NIC side is done; we just need to get those nameservers to stop doing zone transfers and stop thinking that they are authoritative for the zone.
