(70)In order to reduce the risks and consequences of unauthorised or incorrectly executed payment transactions, the payment service user should inform the payment service provider as soon as possible about any contestations concerning allegedly unauthorised or incorrectly executed payment transactions, provided that the payment service provider has fulfilled its information obligations under this Directive. If the notification deadline is met by the payment service user, the payment service user should be able to pursue those claims subject to national limitation periods. This Directive should not affect other claims between payment service users and payment service providers.
