You can't get away with it.
Transfer the money into a high yield account and make some interest off of it until the bank comes knocking.
seen this so many times it never fails , what would make someone think this would be a smart idea, ONLYYY way i would do something like this is if they put like $100,000 in my account and i was dead ass broke with nothing to lose, i would use about $20k of that to find myself a place to live in south america, find a way to withdraw the rest and bounce out of here forever
other than that dude was a fool for touchin them 70k
shyt happened to me
last year i deposited like 100 bucks in my bank account and it showed up that i deposited 250. i was likebetter pull all this out before they recognize.
a week later i check my bank account and im like negative 200
called the bank and they said it was the fees from overdrawing.
my advice is dont do it, just let them fix the mistake.
