For future reference to people reading this. These people are RU scammers, they aren't ran out of the united states. A lot of the times it's overseas and ran through phone line proxies to lose tracking ability on the lines. I'd suggest if an unknown number calls you and they don't have the same area code, look them up.
I'm saying this because two random "girls" on facebook added me and waited exactly 24 hours messaging me and telling me to text them.
Whereas an RU scammer will get your number and not stop blowing it up.
