I also just got the call. I googled the area code, and 401 is Rhode Island. Since I didn't know anyone from RI, I didn't bother to call back. Looks like it's some kind of scam. I have no idea how they got my number though, because I hardly ever give out my number.
Yea, dont answer this number. Is a scam, specially when you call back. From whatever country they are calling from, they WILL charge long distance to your phone and you wont know. Then when your bill comes from your phone carrier, you cant argue it because you called the number back and those [***] get what they wanted, TO SCAM YOU & ROB YOU!!!
DONT ANSWER, TRUST ME! I am fluent in spanish!!! Dont call it back!
