wallet beat

left my wallet with $2,000(brag) in locker at school gym.
i notice i don't have it 1/2 way back to my room and turn around to go look for it.
i get there and the locker i used is locked up.
i ask the front desk if they can unlock it.
they say to put a note on the locker to return to front desk if wallet found inside.
i give them my name and number.
i leave and go back to my room.
i have a voicemsg saying that the person who used the locker came back to them w. the note and no wallet.
i cancel my credit card.
i get a phonecall back from the gym saying someone returned wallet.
i pick up wallet.
no cash.

WWRJD?

any merit in filing a police report?
