get rich scam

Got a call today 1/31/19 from a representative of the MMSweepstakes Co.  Caller id was JM Kingston @ 876-334-9739.  Identified himself as John Miller. located in Las Vegas.  Says they are having technical difficulties so not sure why name different.  I said, give me a number to call you back and he gives me a 406 number however I called him back on the caller id number and he answered.  Says $8.5million is mine for paying all my bills this month.(seriously, how did he know I did and what a lame story) I'm supposed to go to the bank, open a new account, send them the routing and account numbers and they'll deposit the money.  I was trying to figure out how they make money on this but I ran out of patience to listen to the BS.  So sad that people get sucked into these things.
