I answered a call from this number ... silence at first, then one sentence uttered in (I think) Spanish, and a hang-up.  Sounded automated.  I don't know what the message was - I don't speak Spanish.  I called the number back and got the "You have reached the telephone number removal service - please enter your phone number".  I entered my phone number, the automated system on the other repeated it, and said it would be removed.
