Wants to talk to CFO or CTO

I get frequent calls from this number on two different lines - one is a landline and the other is a magicjack internet phone line. They call each of my phone lines a few minutes apart. No one is ever on the other end. A reverse phone lookup just says it is a verizon business landline from Shelbyville, IN.

This number calls ours business phone all of the time. When we call it back its says it's disconnected.

This person asked if I accepted credit card payments and then asked to see my merchant statements to do a reimbursement audit.  

Received call a few times.  Not sure how it hits my phone as all calls to our company go through auto attendant.  call disconnects almost immediately.  Caller ID:  Unavailable
