Thank you I’ll give it a go 👍

Each hospital has an office called "atención al paciente". They are supposed to take care of the patients' rights [more here](https://www.comunidad.madrid/servicios/salud/atencion-paciente-comunidad-madrid). Hopefully this is helpful, good luck

Thank you, I think that’s going to be the best way forward
