Who called from 3234268335

This number calls our office about twice a month with an automated message "This message is for _____, if this is _____, please press 1".... so I press 1 and then they have you on hold... it doesn't tell you who the company is or anything and I don't have time to sit on hold.

It's a recording sayining they represent a debt collector and they give you an 866 number to call. I have no debt collectors after me.
