Alguna vez mi padre ha recibido llamadas de la empresa de encuestas del CIS, luego esta llamada, depende lo que piensen o le parezcan a las personas, puede ser una llamada SPAM o no, pero realmente es la famosa empresa de encuestas del CIS.

Son del CIS (Centro de Investigaciones Sociológicas), para hacerte una encuesta. No te piden ningún dato personal, no creo que sea ninguna estafa. Yo la he hecho y ningún problema.
