CardMember Services review: harassing phone numbers

I am sick an tired of receiving calls from this company I have even gone so far as to tell them that If I could find out who was doing it id take out a warrant on them.I have also told them repeatedly that we are on the national do not call list ...but none of that has done any Good..I have also contacted the North Carolina Attorney General's Office and filed multiple complaints about this and other telemarketing scams and was told in no uncertain terms they are either unable or unwilling to do anything about it since they appear to be coming from out of the country(which in my opinion ) is their (NC attorney general's office) way of getting out of doing anything to protect North Carolina Consumers from telemarketing scams...
