Who called from the number +1 (202) 697-7547

Tells you to call because of a multi million dollar winnings deposited. If you don’t call case will be turned over to FBI. I called the number back after blocking it. No voice mail. Few minutes later a gentleman called me back asking who I was that I was calling him on his cell phone. Told him that I was returning his calls in which she never left a voicemail. She then asked me my name and proceeded to tell me about this award that’s been deposit into account my name and that I need to answer some questions otherwise the case will be turned over ti the FBI. Told him I know it was a scam but that he should do whatever it is he needs to do. I blocked the number. I am now being called from a different extension of the same number.
