That number is a number for ISS allentown.  A staffing agency that hires for amazon.com

This temp outfit asks you to show up in the wrong city because its robots
mislocate applicants.  I'm in Indiana but they direct me to Allentown, PA.
Corrections sent to IFF staffing do no good so far.  Sloppy and annoying.

I received a phone call on my cell phone.  I don't answer calls if I don't know who they are from.  They left no message.
