☎️ 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 Μητρώο 11 (ΕΕΤΤ) — δήλωση εξαίρεσης στον πάροχο (eett.gr), which enforces the telemarketing rules, and to Αρχή Προστασίας Δεδομένων Προσωπικού Χαρακτήρα (210 6475600) for the data-protection side. ΕΕΤΤ — καταγγελίες καταναλωτών (801 11 000 33) collects patterns and scam numbers.

🗣️ What to say

"I am registered on the do-not-call list / I object to any marketing calls. Remove my number and my data from your records now and confirm in writing. Which company are you, and where did you get my number?"

🪜 Step by step

  1. Register your numberOn the national do-not-call register; it is free and takes a minute.
  2. Ask, record, hang upCompany name, where they got your number, then "remove me". Note date, time and the calling number.
  3. Objection in writingTo the company, if you know it — GDPR Article 21; marketing must stop immediately.
  4. Report to Μητρώο 11 (ΕΕΤΤ) — δήλωση εξαίρεσης στον πάροχο and Αρχή Προστασίας Δεδομένων Προσωπικού ΧαρακτήραNumbers, dates, what they sold. Fines follow patterns of reports.
  5. Block on the phoneBlock the number, enable the carrier's spam filter; report scam calls (fake bank, fake police) to the police as well.

❓ 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.
