From: FiilmoreBank
Dear Mr Bright:
Thank you for your email dated Oct 14 regarding a fee charged to your checking account In answer to your question, the fee of $25 was charged because your average daily balance for the month of September dropped below $5,000 This is in line with the policy that governs your account, which is a Privilege Plus account
To avoid this fee in the future, please maintain an average daily balance of $5,000 in the account Or, you can switch to a different type of checking account The Privilege Basic account, for example, has no minimum balance requirement Of course, it also does not entitle you to the benefits of Privilege Plus status: free checks and debit cards, enhanced online security, and online banking services at no charge
If you would like to make a change, you can contact a customer service representative at 555-2904 Also, because you are such a valued customer, we will go ahead and refund the fee in question However, this is a one-time action; in the future, any fees will be applied to your account So we encourage you to take the necessary steps to ensure that your account remains in good standing
As always, thank you for banking with us
