INDOSAT Internet Network Provider NOC Contact

[tdonahue at vonmail.vonworldwide.com (Tim Donahue)]

Hi all,

Sorry for the noise, but I was wondering if anyone has a NOC or BGP 
knowledgeable contact with INDOSAT Internet Network Provider
  (AS4761).  I have emailed the hostmaster@ email address listed in the 
WHOIS contact, and tried calling the phone number listed as well 
(disconnect message).

They are announcing one of our prefixes and I am trying to find a 
contact in their company who can fix the announcement.

Tim
