A lady called and said she was from Infinity and asked for the owner.  I asked her what this was in reference to and she said she needed to talk with the person who was in charge of printing supplies.  I said that would be me and I wasn't interesed.  I hung up.  Scam probably.

More than likely a scam.  Lady called up asking for the person in charge of printing supplies. That would be me, but I said I wasn't sure, could I take a number and have whoever is in charge give her a call back?  She said that she had no return number and she will call us back.  No return number? A legitimate business would have a customer service number to deal with orders.  Sounds like one of those scams that will send you toners whether you want them or not or present an invoice hoping the A/P department does not pay attention and pays it anyway,

They're obviously trolling the internet, looking for businesses.  Our number belonged to a home health care business over four years ago (that's when we got it), and thanks to a couple of websites that don't update their information we get calls like this constantly!  Grrrr...

I let it ring but they didn't leave a message.

They are still trying the toner scam after all these years. The [***] has called 2 days in a row from this number.
