a man called 'Donovan' from Mile High Contractors in Tucson, AZ called trying to sell something acting like he knew me, but I've never heard of him or the apparent company he's claiming to work for.  I got his number so I could call him back, but was different from the # he originally called from.  I tried to call on the original number he called from, but was already disconnected.   I then called him back on the number he told me to call him at, he got mad and hung up, so I called again and he was real mad when I asked what company he's with and how he got my number, etc.  He was almost irrate about my questions.  I told him never to call me again.  I'm sure this is a SCAM.
