Se hacen pasar por Naturgy. Incluso tienen mi nombre y dirección. Me dicen que toca renovar el contrato. Le digo que siempre se renueva automáticamente. Me empieza a meter un rollo, como ve que no me convence, me cuelga.

Me llamaron diciendo que era de Endesa y que yo tenia la luz y el gas con una intermediaria y que ellos son los que suministran, me hace oferta, acepto, pero que me envíe informacion por mail, pide datos bancarios y al decirle que primero me envíe un mail con la info, me dice que sin los datos bancarios no puede enviarme la info. Rechazo oferta.

Dicen ser de Naturgy, por mas que los bloquees te llaman de otros números, hoy cuando les he contestado que no me interesa la oferta y que no me llaman mas, ni me han dejado terminar la frase y me han colgado, increíble por acoso telefónico y mala educación de los teleoperadores
