If she does not correct her behavior or we do not hear from her for apology by post to us in 7 days from the date of this letter, we shall report it to police accordingly.
The above is a part of content in warning letter, pls me to check if it is correct in grammar.
Thank you so much.
It's a very wordy and awkward sentence. It can be more simply and clearly stated like this:
If she does not correct her behavior or apologize by July 9, 2008, we shall report her behavior to the police.
