Person called from 313-483-8028, did not give a name.  Said he needed to speak with a particular employee, it was an emergency.  We did not have this employee here.  Said I could take a message and referenced ticket number ID10T.  I laughed & they hung up.
I called back, got the same person (no name but had the same voice & accent) & asked that our number be taken off their calling list.  Let them know we did have an employee & the prior caller (still same person) was rude.  The man on the other line said, "We do not make calls such as that.  I am a good Christian man & I would never do something like that...(stifled giggle).  You must have the wrong number.”
I let him know that redial does work and do not call our company.  Simply hung up.
Do not take calls from this childish company.
