I answered and they were gone. Sometimes all these "scammers" want is for you to call them back, and then when you do, they find a way to add charges to your bill. Additionally, you may be connected, without your knowledge, to a person in a foreign country and the bill could be large for this call. Don't call them back, and I agree with others, don't offer a verbal "yes" to anyone you don't know.
It says students loans on caller ID but it's Bridget from credit card services who has been calling for the past 2 years with a bunch of different numbers
