It is still possible to contact your EU permanent representative group via email. Op link in "what to do" section has a precompiled email which you can send to your permanent representation group.

As little as it may be, I sent it to the Italian representative group, to the team that oversees telecommunications

Edit if you're Italian you can find the email(s) here, scroll to trasporti e telecomunicazioni https://italiaue.esteri.it/it/chi-siamo/
