If you are seeking to obtain copies of YOUR OWN account history from B of A, simply start with going on-line (assuming you have on-line access) and re-print copies of all your account statements. B of A normally will have 6 months of prior statements available on-line. Second, if you are aware of specific charges that you did NOT make, and then dispute each of those transactions.
BUT, make sure that you are also NOT confusing monthly bank "charges" and/or service fees (i.e.: monthly account fee, other ATM use fee, etc.) with the amounts in dispute. Bottom line is that the bank has a 100% "zero fraud" protection; so any charges that were made by someone else you will receive 100% reimbursement upon dispute/proof of the same...Good luck!
