Product: Checking or savings account

( Letter sent to Chase XX/XX/XXXX ) I am writing to you in relation to the Insufficient Funds Fee charges that have been applied to my account, as above. I believe that these charges are excessive and do not reflect the real cost incurred by you in relation to the management of my account. 
The first fee was charged to my account on XX/XX/XXXX and the last charge was on XX/XX/XXXX.The total amount charged to my account is {$3300.00} in which only {$710.00} was refunded back to me. The fees were described as being insufficient funds fees for the following : charges for paying checks and over your limit fees on debit transactions paid from overdrawn account. Checks that posted at the end of the business day or later in the evening were placed before debit transaction that were done while the account was sufficient to overdraw the account and caused each transaction to be charged separate {$34.00} charges. I repeatedly called customer service about these occurrences and asked them to stop paying charges made to the account if the account didnt have funds. They refunded partial amounts of the charges but eventually refused to help after I reached the limit of courtesy refunds. I request repayment of the fees and charges that have been charged to my account over and above an amount that is reasonable for the process of dealing with these defaults. I will consider any evidence from you that presents information to the contrary but past phone recording will show on several occasions I asked the customer service person to stop this from happening and I finally spoke to a consumer protections agency that has advised me to write this letter and point out that I should have been opted out of the overdraft protection when I initially requested it in XX/XX/XXXX when I was charged a then staggering {$380.00} in overdraft fees. This year alone I have 5x that amount in charges and it is only XX/XX/XXXX I  have been dealing with hardship since I was laid off from my fulltime XXXX job and have been struggling to stay afloat since then. Most of the charges that were made to this account should have been declined and in the case of the debit charges made while the account had funds would not have resulted in the charges. The XX/XX/XXXX law clearly states that I have a right to opt out at any time especially when I made the clear statement to not pay a charge if the account does not have funds. Given these circumstances it would be unconscionable for you to In light of the above, charge the insufficient funds fees to my account. Please refund these fees because I have been very happily banking with you for 6 and the half years and because relative to you and the fact that the terms imposing these fees are not reasonable. 
In addition the terms of my account contract imposing these fees is deemed unfair and contrary to the requirements of good faith and in all the circumstances, these terms cause a significant imbalance in our rights and obligations under the account contract, to my detriment as the consumer in this relationship. I have attached highlighted copies of the YTD charges for the last 6 years as well as the transactions described in this letter. I await your response. 
Thank you,
