First Niagara Bank Bank Account Or Service Complaint

First Niagara Bank Bank account or service department,

Checking account Deposits and withdrawals Pennsylvania

Are banks allowed to post checks to a checking account before a deposit even if they both are posted on the same day? First Niagara Bank does this and I think that it is just a way to get the extra charges for themselves. Yesterday my Social Security check was posted and I has a availabe balance of - after everything was taken out. When I looked at my account today they posted a check and charged me - for it even though my balance was much higher than the - check that was posted on the same day. This bank are a bunch of thieves. I live on Social Security and I 've had some times when I have overdrew and I know that it is my fault but to manipulate the numbers for their own gain is just wrong.
