I don’t know how there can be that kind of error and that definitely sucks. I’m sorry that happened to your mother.
Usually when an ATM is opened and funds are registered there are two people including a manager to confirm deposits. I imagine there is video surveillance at the ATM as well. It’s very difficult and highly risky for a teller to steal. As you can imagine banks take extreme measures to prevent this. I suppose it could be investigated further or maybe even some type of insurance claim could be filed but I imagine the burden of proof would rest on you to prove.
On my old ATM I could insert an empty envelope into the machine and enter a deposit for any number I chose but it wouldn’t be confirmed until the teller actually receivd the funds from the ATM. Now i’m not saying that this was the case but maybe there was an error in entering digits or funds were returned and it was imagined that this was a withdrawal or something. When i was younger I used to constantly have problems with banks and tellers and 99.9% it was my error somewhere. Now with tracking my funds online, fees etc. I never have issues and never need to balance my checkbook because I can tell instantly if a check has cleared.
The ATMs I use now with CHASE are amazing. I can deposit a handful of up to 50 LOOSE bills and it counts them and lists them according to denomination asks me to confirm the amount and gives me the option of depositing. If I disagree with the number it will return the cash. Likewise with a check it will actually show a photo image of the check and print a photo on the receipt. So far it’s worked flawlessly and the best part is that I don’t even have to fill out a deposit slip.
I’m sorry I can’t offer you more help but to pursue this with litigation would me WAY more trouble and cost then the return on the investment in a lawyer.
P.S- I never even enter a bank if I can help it. Tellers apparently are fed Demerol or something to make sure they don’t get too fast.
