Who called from 2122798618

Got a call on my land line.  The man asked for the owner so I hung up.

I received a call from this number Thursday, January 12th 2012. Person on the other end asked me who handles our Visa/Mastercard merchant account (I represent a business). I told them that my accountant was unavailable at the moment, and asked who was calling. The caller promptly hung up after I asked.

Man called my land line.  I hung up when he asked for owner.

who is this?
