People who have not paid any community fees yet will be informed by letter or e mail. If they do not pay within a specific period (I am not sure what this is), Adfinsur will then start to take legal action. They can also legally change the locks on apartments of those who have not paid to deny access.
Since the last list of debtors was published by Adfinsur, the debtors on that list has diminished quite significantly.
