i’m going in circles here

My school: Yes, we can see why you are unable to get your course accredited. Your teacher only noted that you passed, but never got you a grade. Just ask him.
Me: He has retired.
My school: Just ask him.
Me: Hey, sorry to disturb you, but are you by any chance able to give me a grade for that course I took one year ago?
Teacher: I’m really sorry, but since I’m no longer a member of the school and therefore can’t access the grading software, I can’t.
Me: Hey school! Teacher is unable to do that.
My school: That’s too bad.
