Digitcom Service/Wildgate Wireless is the company which provides the ANI's to the call centers responsible for the pre-recorded calls.
I have alot of information regarding these calls, especially where they're calling from.
I'm currently involved in a major Class Action Law suit against the call centers whom are are calling on behalf of National Dealers Warranty and others as well.
For more information on the suit, go to my site:
