I received a notification that the military office will restrict my rights

Here and here, I shared posts about how I got a military summons and how I sent my data to clarify everything. However, I still haven't received any answer to my letter. Instead, I got a notification saying that they will restrict my rights because I didn't come to the military office. The thing is, I shouldn't have gone there on legal grounds because I was sick that day, which is a valid reason for not showing up. However, the letter says that I didn't have a valid reason. So now I have two thoughts: either they declined my reason for being sick, or this letter is just an automatic notification.
