You should ask for a Subject Access Request, it will have a lot of information and documents regarding your account.
i have copied the passage below from the AIB
"Under the Data Protection Acts you have the right to see the personal information we hold about you. Our fee of €6.35 for this is currently being waived. To get a copy of this information, write to your local AIB branch or to: the Subject Access Request (SARS) Unit, Allied Irish Banks, p.l.c., 4th Floor, Adelaide Road, Dublin 2."
I also copied this from an independent article from 2013
"The 1988 and 2003 Data Protection Acts give anyone the right to access personal information held on file by a private business or state institution simply by making what is called a Subject Access Report request.
Under the little-known law, any customer can get these details.
One small business owner in Tipperary said he gained access to more than 20 years of his bank account files, including internal letters sent between managers inside the bank that he had never seen before by using the Data Protection law.
The cheap right of access had been a "game changer" in helping him to uncover historic overcharging of interest that he said amounted to tens of thousands of euro.
He asked not to be named because he has not yet reached a settlement with his bank over the true sum owed.
The price of accessing bank account information using the data protection rules can be a fraction of the cost of ordering copies of historic statements."
