I got the same thing today..I did not answer it nor they left voice mail...

some body called to me which is unknown

8580321111...Name not found...Guess what you %/#!÷€*&^=÷ idiots "You Are Now Blocked" So go and %=÷€&^/#=÷ yourself

They have called twice asking if I make frequent calls to Ghana.  I told them no twice now as well as telling them not to call my number again.  The second time caller began to talk over me saying that there are benefits to what she is offering me.  I told her again, that I don't call Ghana and that if she calls again, that I will report it.  The caller never told me who she represented.

They called me and i asked them how you got my number. I was trying to be funny and he hanged up on me. Later on called me again and started cursing out and he was only doing his job. Great customer service i say.
