Who called from 5044546560

They asked for a specific person, and said they are from the Postal Service then confirmed the name, then hung up.  Scammmer

I just looked this number up. It belongs to Ruth's Chris Steakhouse in Metairie.

Not sure where you got that information but the Ruth's Chris STeakhouse in Metairie, LA website, shows an entirely different number. Call back to this number gets, "you have reached a number that has been disconnected or is no longer in service."  It's spoofed.  Therefore it's a SCAM.  Block the number.

Got a call from a loud noisy call center and some guy with an Indian accent said his name was Rusty Miller and White Associates(???).  I asked him if this call was from INDIA and he hung up.

Then 454-6560 must have been the old number for Ruth's Chris because when I googled the number I saw Ruth's Chris listings with that number.
