Who called from 5140011000

Have received FREQUENT calls with the same female voice recording but numbers are always different. Same credit card message to which we never respond.  I am  very concerned as they are now coming to our cell phones continuously - approx. every 10 days or so; and we are on the National Do Not Call list. Would like these to cease.

called .....no one answers

How do there get your information do you hav to talk to them and give them it or can they get it though your mobile phone?

ive blocked them too but then they just call from a different number.

the called me at 715 AM cst, too f-ing early for a business call!
