Can I retreive a bank statement from 2004 if my account is closed?.

In 2004, I made a wire transfer of $80,000 to a bank in Korea. 9 years later, I am being sued that they have not received that money. I called my bank at the time, Wellsfargo and asked to see if they had my bank statements/wire info. Wellsfargo told me that they only keep bank files up to 7 years and told me they could not find any records. I need to find this record of wire transfer that was made from Wellsfargo to fight this case. Are there any legal ways in which I could have access to Wellsfargo's database in which they sent $80,000 to a bank in korea?
