I got a call yesterday from this number also but when I called back I got message saying I didn't have enough funds on my account to make this call

I gotten calls from this # on 11/27/12, 11/13/12, &10/29/12. All on my cell phone which I have them block. My phone just tells me when they called.

Pressing any number to speak to an agent is the wrong thing to do, even if screaming at someone or blowing a whistle will make you feel better.

Pressing those numbers only confirms that your number is a valid one.   You've just targeted yourself as a sales lead.  

I made that mistake too.  Instead of getting 1 or 2 calls a week,  they come in at least once a day now.

I have gotten multiple calls from this number with no voice mails.  I dont answer calls on my cell from numbers i dont know.
