Who called from 7408344000

This number tried calling me 3 times in a row.  I'm at work.  Rejected calls.  Don't know who they are. Don't have a Citi account.  They never left a message.

called mid afternoon on a sat left a vmail with a 4# reference for someone I dont know. I have had my # for years

Just got a call.  I opened a card with Sears last weekend.  They were double checking making sure it was really me who opened the card.  CITI holds Sears credit i believe.

multiple calls,can hear typing in background,but no one speaks

Left message about someone trying to take out a card in my name but I was unable to replay the voicemail that contained all of the necessary information.
