50 Section 125 Unlawful use of a communications service A telecommunications operator shall close a communications service or prevent its use without delay if the subscriber, user, the police, an insurance company or another telecommunications operator reports that a smart card used in managing communications service has been lost, that it is in someone’s unlawful possession or has been unlawfully used and requests that the communications service be closed or its use prevented. The subscriber can be held responsible for unlawful use of a communications service only if the disappearance, unlawful possession or unlawful use is due to the subscriber’s or user’s more than slight negligence.

Section 128 Joint responsibility of the telecommunications operator, service provider and seller A consumer who has the right to refrain from paying or receive a refund, compensation or other payment from a business operator due to the operator’s breach of contract shall have the same right in relation to the telecommunications operator that has charged the consumer for a
