All you need to do is the following:
Hop on to your Harmoney dashboard.
Click on the 3 lines showing in the top right corner of your dashboard.
Select "My Loans".
Select the loan that you want statements for.
Scroll down to the "Download" button.
If you click on it and it doesn't show the download notification, there is a chance that your statement is in your downloaded folder on your device.
If you've clicked on download and it still doesn't show anywhere on your device, do let us know and we can look into that for you.
