Same thing happened to me. One day I got $700 in my account and a transaction record never showed for it. It was the only money in the account at the time and I even went to the ATM to withdraw it. 4 days later my account was in negative and the bank called me telling my it was a system error and I was due those fundsIt's happened with my sister in law few months ago and she spent the money and few weeks later the bank said that was mistake and she need to pay it back
Don't do anything and let the money stay there for a year or two, than spend it![]()
