Telefonica network contacts to resolve reachability issues.

Is anyone from Telefonica around that can help debug some technical issues regarding reachability to a number of prefixes across a few ASs? The contact info on puck.nether.net bounces and info@us.telefonica.com is a bitbucket from all outward appearances. This has been going on for at least a month with no fix or reply to emails. Here are some example IPs that aren't reachable: (host, asn, ip) ns1.everydns.net | 15135 | 208.76.56.56 ns2.everydns.net | 3557 | 204.152.184.150 ns3.everydns.net | 26228 | 208.96.6.134 ns4.everydns.net | 3356 | 64.158.219.3 Thanks.
