they are not from north carolina they will call you under various numbers. they take a week break after you tell them they are number one then they call from another number. 205-639-0290,  803-626-0299, 714-676-9441, 803-295-5808. the way you can do VOIP now  they may not even be in america. i wish you could reverse detonate their phone on their ear now that would be worth the call.....
