Can they do that without my consent?
How can they use the money when its already pending for something else?
What can I do?
Yes they can. You can't just expect the bank to ignore the fact that you stole from them & not try to get their money back.
You owed the bank FIRST because you were overdrawn. Yes, they can take what you owe them first. Wouldn't you if someone owed you money?
Nothing you can do other than get your finances in order.
so... you tried to steal from a bank and are mad they got there money back?
you must have put the money in the wrong acct
