Old Mutual online website frustration

I have invested millions in an Old Mutual Retirement Annuity (in 2021) Not complaining about their fund management or growth. But their online website is a disgrace -- Specifically the section where a client can view their details, beneficiary nominations, % splits etc etc. One day you look and all seems fine. The next day the screen info has disappeared, or is missing, Maybe it's just my poor luck, but I've been fighting with this webssite on and off for years now. Credit to my financial advisor who admitted to me that OM is aware of their shaky website, an that I.T. is working on fixing it. So that's good news, but why don't they temporarily close the site, fix all the problems, then bring it up again. Meanwhile clients (me) must wade in confusion. No man, this is not fair. It depicts OM is a bad light and that is not good company / client relationship building. Rant over !
