Found I had 10 missed messages from this nimber.

Call back and receive an error message instructing me to call customer care but has no business name or call number.

Same number called and left no message. Unable to call back

Called my cell today, 11/10/16 at 2:35P. Recorded msg to the effect: 'Have you received a letter from your congressman telling you your insurance rates are going up? Press 1 for details, 2 to be removed.' I pressed nothing and got disconnected. I called # back, and got a message that said, "The call you are attempting to place is not allowed from this line. Please dial 611 for customer service or  dial 1-800-331-0500 from a landline phone. [Then something in Spanish that was probably the same.] Message 10, US01LV." That was an ATT number, which is my carrier. Not sure why I can't call the number back. Did not try calling ATT to find out.

it's a scam, ignore it
