Timadores, te dicen que te has dado de baja de Endesa y que te van a cortar la luz porque no pueden emitir las facturas, y te piden tus datos para evitar que te den de baja. Les he dicho que me lo envíen por correo, si es verdad, y me han dicho que me dan de baja de Endesa y me han colgado. ¡Estafadores!.
