Woman called to tell me that toner prices had gone from $450 to $510, and that she could get me one more at the old price.  She knew my name and where the copier was located in our office.  When I asked if we had ordered from them before, she hung up

Yvette called asking for copier number. Hung up when I asked where she was calling from.

Classic copier/fax scam.

A common scam, they then try to bill you for the copier supplies.

She called asking for information on our copy machine. Then I asked who she was and she hung up.
