Who called from 7408341493

Got three calls and no answer, weird.

It's Citicards.  Called twice last night with no messages left.  Called just now and left a message.

calls all the time, leaves no messages. when they call it shows up as delaware OH

They call my phone 7-8 x's a day, when I call it right back , it always says its been disconnected. How do you block the number from your phone. They call my cell phone! Go figure how they got that number. :(

Just picked up its Citibank. I owe debt.
After giving information and secuirity questions, I was worried if they were SCAMMERS???
Who calls from 740 area code and ask for information and ask if I can pay some money? I didn't have money for them but sure did have some answers to their questions. I would think they call from 800 or 888
