Call came up as RedHat, Inc. and the individual stated that I had a DHL package that needed to be delivered.  I asked him who the sender was and I could not understand what he said as he had a heavy accent.  It sounded like a call center in the background.  He asked me if this was my personal telephone number and i stated it was a business line and he hung up on me.

Calls asking for employee, when informed not available they hang up. Called again back to back asking for former employee and when told they no longer worked here they questioned my answered then hung up.
