Called at 5;30 am, didn't answer. No message. These credit card scam morons have called me many times before, somehow they never figure out that they are wasting their time.
It's a complete scam going on at the moment. They're fishing for your personal information. I get 3 of these calls a day--always from a different number in a different state. I don't even have credit cards and haven't for over 5 years, so I know it's not legit.
