Se hacen pasar por Naturgy (sector energía) ofreciendo una supuesta bajada del precio del suministro (mencionan bajar de 0,29 a 0,22) y anuncian que la factura llegará con el mismo color pero distinto nombre. Operan por teléfono con llamadas repetidas en varios meses y, según usuarios, podrían proceder de un call center (mencionan prefijo 87340 y 'COLT').

Likely purpose: Suplantación de Naturgy y oferta fraudulenta para cambiar la comercializadora y bajar el precio del suministro
