Received a call from this number.  It came up as "unknown" with this phone number.  The lady on the other end said her name is Amy and she is calling for Cartridge World in Saginaw.  She asked to know what printers we use in the office.  I told her and then she wanted to know my email, who we currently buy ink/toner from, etc.  I asked Amy if she was actually in the store in Saginaw.  She said she wasn't, but she was calling on behalf of them.  I asked Amy her last name and phone number.  She gave me Cartridge World's phone number and then didn't tell me her last name.  Instead, she started asking me more questions.  I didn't answer her questions, and I asked her her last name one more time.  I could hear her fidgeting on the other end of the line.  I asked her once more.  She didn't respond.  I asked her if she was ignoring me.  She hung up.
