That’s the first step of escalation. If they don’t comply, you can threaten them with/kindly remind them of the italian data protection laws (you’d have to research those on your own). If they won’t comply then, you can issue a GDPR request. According to the GDPR, you can always demand your info being deleted. no matter, what you signed beforehand. If that fails: talk to the press and/or get a lawyer.
If you do that, make it public, or else you can get profiled again.
