Beneficiaries not being saved on MyLiberty portal

MyLiberty portal is not saving new beneficiaries despite giving a success message.

When I log back in a few days later they are gone. I try again and the same thing happens.

I notified customer support and they do nothing apart from sending me a manual beneficiary form to fill in.

This issue is huge and a regulatory violation: People think they have updated their beneficiaries and they are not. Your support teams ignore me when I complain and report the bug in detail and ask them to escalate to their dev and compliance teams and notify their customer base of the issue. No one does anything. No one cares!
