Telefónica SA

Telefónica had charged the complainant different fees in relation to the operation of a telephone line that the complainant had never heard of. The reason was that the complainant's bank account was linked to another Telefónica customer, which meant that the charges were debited from the complainant's account. In the AEPD's opinion, this was in violation of the principle of accuracy as required by Article 5(1)(d) GDPR. Authority: Spanish Data Protection Authority (aepd)
