I received a voicemail message at my office indicating the caller was Katy Hall calling from check fraud dept of Florida Proceesing. I called back once, and when they answered I indicated 'your call is being recorded for quality purposes.  I work for a phone integrator and I was recording the call, so I had to state so up front. They hung up.  I called back again, asked for Katy Hall. The person who answered asked me my name. I advised again I was calling for Katy Hall and she had left me a vm message.  The person asked be who Katy asked for. I advised she left me a message to return her call and if Ms Hall wanted to speak with me she had her chance.  Then I was asked what phone # Katy dialed to reach me. I told them I don't know as there are a couple of different #'s that can route to my extension in our phone system.  I asked why not just look at the caller ID as we were on the phone?  
The lady just let out a huff and hung up.  .
