Received telephone call from 972-725-0016.  Man with American accent asked for the IT Manager.  When I asked who was calling he said his name from IBM.

He hung up while I was checking the number.

6 one-ring calls today.

IT sales call

Female caller asked for a name of someone not at company.  when informed wrong number said well give me sales manager.

Never said why or who they were with.  Refused to leave any information or identify who they were.  Persistent to try to reach the sales manager wanting numbers and times they would be available etc.

Extremely pushy.  Hung up on us when we refused to give them the cell phone number.

Gentleman requested to speak with (name), our companies IT Controller.  I asked for his name - Ryan Clifford - and who he was with - IBM.  I then put him on hold so I could research number.

I informed him she was not available and if I can have his number so she may call him back.  He stumbled around the idea and informed me he was "half-day" today, and he would be out of touch.  No number given.
He asked if he could call back on Monday, that it was real important he speak with her regarding something new they had to offer.
I told him sure, that way I can retrieve more information from our next chat to report here.
