Hi @Adán, sorry to hear about what has happened. 
I have translated your question to English as this is an International forum, please post any replies in English and will be easier for me and other users to assist you.
We do not have any service where you can remove a screen lock without resetting your device by performing a software repair. Do note that in this process all data stored on the internal storage will be deleted.
I hope that helps!
