A woman was stunned to discover that she had $1 billion sitting in her bank account.
Julia Yonkowski went to withdraw $20 (£14.40) from an ATM last weekend and found out that she had $999,985,855.94 (£719,984,816.35) in her account.
Yonkowski, from Florida, became the 615th wealthiest person in the US with the millions in her account but says she was "horrified" by the sudden influx of cash.
She told WFLA: "Oh my God, I was horrified. I know most people would think they won the lottery but I was horrified.
"When I put in for the $20, the machine came back and said we'll give you the $20 but that'll cause an overdraft and you will be charged and I said, 'Oh just forget it.'"
Yonkowski revealed that she struggled to contact the bank as the incident happened over the weekend.
She said: "I just can't get through. I get tied up with their automated system and I can't get a person."
