46 The terms of a time-limited communications service agreement shall not be changed during the agreement period to the detriment of the consumer. The terms can, however, be changed because of legislative amendments or decisions of government authorities. A telecommunications operator shall notify the subscriber of any changes in the agreement terms no later than one month before the amended terms enter into force. A telecommunications operator shall inform the subscriber at the same time of his or her right to give notice of termination with immediate effect if the subscriber does not accept the amended agreement terms. Section 115 Closure of a communications service or restriction on its use A telecommunications operator has the right to restrict the use of a communications service or to close it if the subscriber has not paid a matured payment for that service. The closure or restriction right does not apply, however, if: 1) the matured payment is less than EUR 50; 2) the matured payment is for receipt of a service other than a communications service; 3) The matured payment is paid within two weeks of the date on which the request for payment is sent; 4) the consumer proves that the neglect to pay is due to illness, unemployment or other comparable reason beyond his or her control, and the matured payment is paid within one month from the date on which a request for payment is sent; 5) the subscriber submits a complaint about the bill before the due date and pays the undisputed part of the bill by the due date. A telecommunications operator also has the right to close a communications service or restrict its use if: 1) the subscriber is declared bankrupt or a public authority has found him or her to be otherwise insolvent and the subscriber does not set a reasonable security; 2) the subscriber does not comply with the other agreement terms, despite a request to do so; or 3) the subscriber or user has been charged with a disruption of communications using a subscriber connection. A telecommunications operator also has the right to restrict the use of a communications service if the user exceeds the spending limit referred to in section 112(1). The telecommunications operator shall inform the user in advance of restricting the use and shall instruct the user on how to prevent the restriction. A telecommunications operator shall have the right not to connect calls or otherwise bar the use of such a communications service if it is evident that the service seeks unlawful financial benefit and if fees resulting from the service accumulate on the subscriber’s communications service bill. The provisions in this section regarding a telecommunications operator’s right to prevent the use of a communications service does not limit the operator’s obligation to restrict such use by competent authority or court decision. Section 116 Terminating an agreement The subscriber may terminate a communications service agreement orally or in writing. The subscriber has the right to terminate a communications service agreement valid until further
