Bank of America systematically post the largest amounts first (in Descendent order) in a transaction's day. So if you had 7 transactions in one day they will post the biggest amount first.
For this reasson, I have 7 overdraft charges. If they had posted the smallest first and go in ascendent order, I would have only one overdraft charge.

I spoke with the Branch manager and he told me that he could not help me, that that was Bank of america's design of posting charges.

Is there anything I can do?

Thank you.

Yes, keep a bigger balance, get overdraft privileges or change banks.

I have checking with Citibank, with an overdraft protection line of credit. As long as I put money into the account before close of business, any draw on the overdraft account is reversed.

Overdraft fees are a lot more expensive then a couple of days interest.

Doubt it... you apparently agreed to have 7 automatic payments taken from your account on a certain day, it's up to you to make sure you have the correct amount in the account.

And they probably do larger transactions first to that people's automatic deposit paychecks will deposit before their bills come out... though I'm no banker, just a thought.

Sorry, this is their policy, they love to make money from charges. So all you can do for the future keep enough in the bank to cover all of the charges

Despite what banks want people to believe about being there to help, in actuality of it is that they'll help as long as it is to their benefit!

They are completely aware that they will make more money if they bounce 7 checks as opposed to one large one. They can justify their policy however they want, and the only thing you can do is follow the advice to always make sure you have enough in the account to cover everything.

I'm not being mean or condesending... believe me, I've paid banks way too much for the privilege of having an account.
