Few if any of them permit outside contact. I remember having to get a customer to escalate their PSN case after removing the GEOIP configuration because PSN didnt reflect the change immediately. Its really difficult from a customer service perspective, because the error messages tend to pin the blame on the ISP, despite it wholly being a circumstance of the content owner. You do get lucky, IIRC theres a few blog posts where people go into detail about how to contact some providers, but I found that some of them rotated those emails pretty regularly.
