Call them. Posting here won't get you an immediate solution that this probably requires.
It depends how you found out you were hacked. If you have an AUP ticket open, then respond to it, since Abuse handles the investigation of abuse tickets.
Calling up will not do anyone any good, since the investigation will take time(to do it properly). So if there is not a ticket open already... create one.
