	Well, a 'normal' solution (short term) would be to announce more 
specific announcements of your address space, then contact said Telco's
upstream providers to have your prefix filtered from their connection(s).
A nicely worded (polite) email/fax would go a long way with the NOC.

	This is of course, if they are not returning your calls, or as
you say giving you the run around.   I would also try to find a sympathetic
body at the telco to help to properly resolve the issue, so you can go back
to announcing only your aggregate netblock.

	ARIN will not step in here.  They allocate resources, they do not
police or enforce those resources.
