Seeking RM 600 Back To My Hand

Finally sent a message to my lecturer to ask for my RM 600.
He replied me, He even not seen the shadow of my face, how could he give me back the money?
Replied him, Sir, will you be free on tomorrow afternoon? I'll go to your room and take from you.
He doesn't reply me anymore.

I need money.
Wishing that he will give me back the money when we meet tomorrow...
