Transaction Data for CSV File - Chat Unable to Help

Is anybody else having problems downloading transaction data older than six months to a CSV file. It's not even that I've got as far as trying to create the CSV file, it's more the data is just not showing after marking the calander. It's not pulling the data. Chat escalated the issue, sat on it for a week and came back with please use 'Statement Flow Order Option' this option does not exist!!!
