SunRocket, the defunct VoIP service provider, is suing Vonage for playing dirty tricks by illegally obtaining SunRocket's customer list. Vonage wouldn't play dirty tricks, would they? Surely, Vonage wouldn't do stuff like I don't know - charge you a monthly fee after you canceled service with them and ported your number to another phone provider. No, not Vonage. Canceling Vonage is as easy as pie.
