En la pantalla del móvil aparece como CIS Centro de Investigaciones Sociológicas. No he contestado y no lo haré por si fuera una suplantación de identidad con estafadores encubiertos bajo un nombre que nos suena "normal"

Pues a mí me acaban de llamar de ese numero y dicho que es para hacer una encuesta sobre la calidad de la democracia con una duración aproximada de 15 minutos, pero no la he atendido porque iba a salir de casa.

Esta gentuza no para de llamar. Chorizos no coger llamada y bloquear. Voy hacer un escrito a telecomunicaciones a ver que les hacen a esta gentuza (una denuncia y también iré a comisaria). Tenemos que estar a todos los que nos llaman como un equipo e intentar parar todos estos acosos estafadores que se les termine de una vez por todas el saqueo a muchas personas. Que gracias a Dios no es mi caso. ¡Unión y equipo!. Suerte...
