I'm assuming the caller was a debt collector looking for a person who hasn't had this phone number in over ten years (we used to get collection calls for her all the time). He said must have some wrong information and apologized for bothering me. The caller display shows "Citizens United".

keeps calling our mobile number

Citizens United is a Conservative political group. Probably soliciting funds.

"Citizens United is an organization dedicated to restoring our government to citizens' control. Through a combination of education, advocacy, and grass roots organization, Citizens United seeks to reassert the traditional American values of limited government, freedom of enterprise, strong families, and national sovereignty and security. Citizens United's goal is to restore the founding fathers' vision of a free nation, guided by the honesty, common sense, and good will of its citizens."
