The area code is located in Iowa ~ I WOULD NOT RESPOND TO IT AND HANG UP... My gut tells me it is a scam! If you HAVE a credit card call the number on the back of your credit card. AND NEVER give up any personal information over the phone....even if you THINK you know who is calling, always call the number back after finding out where the call has originated. If it truly is your credit card company again, call the number on the back of your credit card.
Too many scams going around right now and too many people praying on people who are in most circumstances already financially strapped so don't 'throw grease on a fire.'
