Of course this isn't a 'real' company. This is a boiler room which may be in USA or may be off- shore.
Never call these numbers back. Totally a scam. Your number has reached them because you answered numbers you don't know. Press 1 to be put on the do not call list - hey, good luck with that. They just added your number to a list that they will now sell to other bottom feeding scammers.
Ignore this S*^*t. Get a call blocker. Go back to doing something useful.
