Dicen ser de Naturgy, tienen tanto mi nombre y dni como mi dirección postal, además por supuesto del teléfono. Te dicen que te van a actualizar las tarifas del gas (que no tengo contratado con ellios) y que me envían un SMS para "demostrar que es un agente de Naturgy" supongo que ahí debe estar la estafa, en acceder al enlace. En ese momento les he colgado.

Llaman diciendo que son de la "Comercializadora de luz y gas". Pretenden formalizar una actualización, muy favorable por supuesto, del contrato de luz y gas. Dicen ser de Naturgy. Pretenden que les dé datos personales. EVIDENTEMENTE no se los doy.

No he descolgado. Es una pena. Puedo estar perdiendo algunas llamadas por tanta intromisión.
