Al descolgar escuche un pitido y sin contestar a los 3 segundos se corto. Supongo que son maquinas para detectar los telefonos validos y seguramente si contestas son capaces de detectar sex0 y edad aproximada. Una vez tienen esos datos meteran tu telefono en una base de datos para venderla a empresas para que comience el "bombardeo"

Llaman embaucando a la gente mayor que vive o está sola , es una vergüenza que halla tantos estafadores en esas líneas comerciales. Incluso les dicen que son de su anterior compañía cuando ni siquiera se molestaron en avisar de las subidas altísimas asustando a la gente que no tiene grandes ingresos con los costes de vida

Digo que estoy en lista Robinson y con desparpajo me dice la tal Dora que no tiene nada que ver que estè con la lista con una "mejora" del contrato. Cuelgo y bloqueo.
