How widespread are spam calls? Think about this for a second: over the last year, nearly 60 million Americans say that they lost money as a result of being phone-scammed for a nationwide total of almost $30 billion.
I just got a call from a number that is similar to mine, it had the same prefix. A call like that is from someone "spoofing" your number. It's just one of the many scam calls we all get that will regrettably increase next year.
