Here's a rundown of exactly what happened

I make deposit. Deposit slip is WRONG. Says wrong amount and does not specify seperate section for cash and checks, only one large amount (I deposited 2 checks and some cash). Few days later, the 2 checks returned. The 2 checks (out of state, personal checks I might add. I don't know why they didn't hold it anyway) had already posted my account, it said money was available. Therefore, once they returned, a bunch of items were insufficient funds because I thought I had money in my account. Now they are charging me a bunch of fees because they had already posted the money in my account.

Am I wrong to think that this is wrong?
