I live in the same area code and my personal cell phone # starts with the "575" prefix (Madison, WI) so I answered this call even though I didn't recognize the number. Big mistake. It's another of the credit card scams - "it's urgent you call us back concerning your credit card to see if you're eligible to lower your rate". Yeah right. So annoying - especially when all of our phone numbers are on both the Federal and State of Wis. DNC lists.
