I had a similar experience as your moms colleague. I transferred 20k from savings to checking. During the process I think what happened is the web banking page froze and allowed me to hold the enter key on confirm that repeated several times. I ended up with 200k in my account that came as a negative 180k balance to my saving account sent to my checking account. (values rounded for story simplicity) This meant that not only did their online portal not have controls to make sure that internal money transfers are confirmed before processing. They also had no controls to make sure that when an internal transfer is done that the money is there to be transferred. I waited a couple days expecting a call. Nope. At the end of week I call them. Get transferred around a bunch. The whole time everyone is saying everything is good nothing is wrong, there is no problem. I 100% certain every single one of them was lying through their teeth while they go the FBI on the phone because of the automatic assumption that the computers are right and I am automatically a criminal. There is no way all those people saw a -200k balance in a saving account and thought it was fine. (BTW that means it is standard bank policy to lie to a customer when something is wrong) So what happened. They immediately zeroed my accounts and froze all my bank activity for three months while they "investigated" Then they only returned 15K of the original 20k that I moved so they effectively stole 5k from me. I spend another 6 months trying to get that money back and did not succeed. I would have been screwed if I had not been born poor and was familiar with the banking system corruption. I have my income,spending,saving and investing split among different banks and banks accounts in case of something like this ever happened. The bank initials are WF.
