Key Cabinet

[Atlanta Z3]

Reported last Friday and no acknowledgement from management. 
This morning I open the cabinet and my keys are out of order.  (They are alpha on one rack and lower rack file cabinet numbers)  I have now removed the office keys from this cabinet and will lock somewhere else.  How can this person come to me that the keys are missing if I don't know they have a key? 
I know my bosses are busy, but this is gross misconduct. 
Side bar, I asked for a key to my desk and had to sign for it.  The office manager told me she is tired of people leaving the company locking stuff and having to pay to rekey.  Also paying too much because people are losing keys.  Once signed for I will have to pay for a replacement key.
