Bank Statemnts in CSV or OFX format not available

Absa can not provide me bank statements for more than a month to download in CSV or OFX format, because according to the Internet call centre, my business has to many transactions and therefore gets archived sooner. Therefore I get penalised because we have a large business with a lot of transactions. How can that be justifiable? Your bigger customers are being negatively treated. I can go to any other bank and get csv files 3 years back. Now I I am forced to enter thousands of transactions maunally in my accounting software. This is a deal breaker.
