Managing an account: Checking or savings account

" Bank of America closed my checking account in one-sided order. They are holding my personal funds in the amount of $1600.00. It has been 30 days since the closure, and the bank has failed to send me a Cashier 's Check or release my money. This is causing me severe financial distress as I can not pay my bills. I demand the immediate release of my $1600.00. ''
