Called my cellphone 10/8/14. When I answered, there was a recorded woman's voice speaking in Spanish. Only info in addition to phone number (1-720-504-6034) was "CO, USA"

I called the number and a recording said, "Press any digit to be removed from this list. This may take 24-48 hours. Thank you."
