Ah, that totally sucks!!!
My dad has a free fraud alert on his account. If his bank account balance changes by $0.01, then he gets a message. It doesn't actually stop people from using the account, which is both good and bad. (You don't want to have to call the credit card company every time you want to make a purchase.)
You could do something like that for now. Those things send text messages when your bank info has changed, and they tell you the day, time, and location of the purchase.
That doesn't fix your money problem, but it can help you monitor your bank account while you try to get this situation sorted.
Also, what about chip card? Those are a little more secure. I want one, but don't have one.
Did you happen to use an ATM recently? There are sometimes skimmers on those things you have to watch out for... because they'll steal your info right away and someone can use your bank account immediately. If you're interested, I can link you to a video that shows how to identify a skimmer. Some guy from Austria made a video
