☎️ I keep getting unwanted sales calls — how do I stop them, and who enforces it?

Direct answer

Cold calls to consumers are banned or opt-in in most EU countries, and the rest have a do-not-call register: register your number once, and every call after that is a fine for the caller. Tell each caller "remove me, I object" — that objection is absolute under GDPR. Report persistent callers with the number and time to Liste Robinson (ILR) / opposition auprès de l'opérateur (web.ilr.lu), which enforces the telemarketing rules, and to CNPD — Commission nationale pour la protection des données (26 10 60 1) for the data-protection side. ILR — Institut Luxembourgeois de Régulation (médiation) (28 228 228) collects patterns and scam numbers.

❓ Frequently asked

They said I "agreed" on a comparison site

Consent to marketing must be specific and separate; buried consent is invalid. Withdraw it in writing and report.

The number changes every time

Spoofing. Report anyway with the times; the regulator traces the carrier behind the calls.

A "contract" was concluded by phone

For consumers, most countries require written confirmation for phone sales; a contract you never confirmed does not exist. Dispute it in writing.
