Muy mala educación, intenta estafa fingiendo ser Distribuidora de Electricidad e inventandose ser la comercializadora y ofrece falsa regulación de tarifa por falsa subida en tu actual contrato sin saber que tarifa tienes que comercializadora te factura ni nada. Estafa , mentiras y fraude telefónico... Ojo personas mayores. Dispone de datos posiblemente comprados a hackers tras hackeo a Endesa .Mucho cuidado. En el fondo son unos payasos que no saben la diferencia entre distribuidora y comerciali
