This is a 3rd party telemarketing company trying to "qualify you" for lower credit card rates. It seems like it's proactive Debt Counseling or something of that nature. I actually answered and played along and the guy was rude and refused to divulge any company info so it was obviously a scam!
made it sound like they were MY credit card company needing to act fast to avoid something being cancelled. When I pressed "1" to speak to a rep, she was vulgar and rude when I asked if it was a solicitation. Oh yes, then she hung up on me!
