One of three calls, which are now known as "Neighbor Spam Calls." The spammers use your area code and the first three digits of your number and spoof the rest of the four numbers hoping you will answer and be suckered into their scam.
We have received three separate calls from 520-400-2490, 520-400-9870 and 520-400-7505. We know nobody at these numbers and, of course, refuse to answer any unknown caller.
Beware of these jerks as they will try and take your money.
