Same here, with the first call on 1/12/15.
On 1/13/15, I received a call from the same number - asking for a person I know but who has nothing to do with my number.
I am not sure who the person are company that is calling but they have called me several times and refused to speak. They keep calling and when I pick up they either hold the phone or hangs up. It very annoying and would perfer if they didn't call my number again.
