Cable and Wireless Antigua

Hi there, I have gone through all normal channels to try to get through to someone in Cable and Wireless Antigua (LIME). It seems difficult to get a fast response through normal channels (it can take up to 48 hours some times to get a response to a "network down" situation). Is there any senior admins who deal directly with the transit end on NANOG? I am having some difficulty getting a security issue dealt with. Thanks! Ken
