Who called from 4802640623

Someone with a very bad phone connection (probably a spoofed number from overseas) called and asked for the IT manager.

Received a total of 13 calls last Friday from the same man and woman with accents but from different numbers, wanting to send their "annual report to the IT director in the manufacturing environment."  I told them repeatedly that company policy dictated sending the information via standard mail, not email, nor could they speak with anyone.  It became so bad that I finally advised the woman that she and her associate would be reported to Security if they phoned again and to remove our number from their records.  She backed down quickly, so let's see what happens.  The numbers were:
480-257-7028
480-264-0623 (two)
480-327-6806
480-389-1437
520-265-8472
520-265-8582
520-265-8739 (three)
520-366-3116 (two)
520-366-8814

Just another IT sales pitch, but with a bad pitch.  Ended quickly so I didn't get a ton of details.

Called several times and left no message. When I finally answered, there was no one on the other line
