I'm having the same issue. I needed to do a name change and could not log in. I tried their website and their app, but no luck I called their supposed frequent flier desk and they had me attempt to fill out a form, however, I was unable to submit the form. It t kept saying that I wasn't registered. It's funny because I received an email prior with my frequent flier number and name. This is why I called them in the first place, they had my last name written twice. It's concerning because your name must match identically to what is on your passport. I'm going to see if I have any luck trying to find a number for their IT department. I will post my progress. Please do the same. I'm hoping that enough people complain they will fix this issue
