This number just called and my caller ID listed it as "Illegal Scam" - I almost answered it because I thought that was funny. I blocked the number on my CPR phone blocker.
Got two calls two hours apart I did not answer, when I tried to call it did not even ring just disconnected me. I believe this is some kind of company that has been employed to upset and harass people for personal profit.
Got a call from this number.. here's the interesting bit, the Caller ID was "ILLEGAL SCAM" which I thought was hilarious. I answered it anyway just to see what they said. It was a recording "This is an important announcement. We've made several attempts to reach you because of your credit card..." I hung up at this point.
