Josh Muszynski checked his account online a few hours later and saw the 17-digit number - a stunning $23,148,855,308,184,500 (twenty-three quadrillion, one hundred forty-eight trillion, eight hundred fifty-five billion, three hundred eight million, one hundred eighty-four thousand, five hundred dollars).
Muszynski says he spent two hours on the phone with Bank of America trying to sort out the string of numbers and the $15 overdraft fee.
The bank corrected the error the next day.
Bank of America said only the card issuer, Visa, could answer questions. Visa, in turn, referred questions to the bank.
