Dear Saldana Kozar,

Thank you for your inquiry. We appreciate the opportunity to assist you.

All this ---- $8.43 Quality Food Center and $6.06 listed currently only as Store #1077.--- ,
I payed BEFORE and after that, my AVAILABLE balance was $+10.00
.

Then, I try to pay overdraw so I put around $ + 256.00 on my account. Then I had on my account about $ 240.00.
First, that day around 11am, I bought lunch and spend 8.43. Around 5pm I went to the bank and get 200.00 from that account. My available balance after all this transaction was + 40.00.
I didnt use my card after that.
Below is BALANCE SHEET THAT I SO NEXT MORNING:

Balance sheet is incorrect. First I payed 8.43, then I took 200.00.
So why my sheet look like this???

So now, I own -$73.43 and probably OVERDRAFT ITEM FEE . How much is that fee, I will see today.

Can anyone please answer me, where is my mistake and what are my option, except to close my account. ( I will deffenatly do that today)
