Who called from 5173089820

This number keeps calling and never leaves a message.  I answered one time, but cannot recall the name of the business they said they were from.  They spoke very fast, and made it clear that the call was being recorded.  They asked to talk to me, I told them I wasn't home, and asked if I can take a message, and they quickly refused and stated they would call back later.

This is a telemarketer, I called the number back and the asked me where i graduated from high school. The name of the business is collegematch
