I have done a quick translation of your question, which seems to be:
"Who should I contact if I want to extend my subscription"
This depends on which F-Secure product you're using, for example, F-Secure SAFE is renewed through the SAFE Portal, but there may be different methods for different products. If you could give us a few more details, we may be able to help better.
