Apparently, my Qatar status has been "under investigation" since July last year, hence I am unable to login, and my status is unlikely to be extended. The telephone staff couldn't add any further information and are looking into why I cannot login. I have been calling Qatar and emailing them since July 2020, and have raised a ticket to resolve this back in March, but there has been no progress.
The customer service is shockingly bad and makes Qantas look stellar in comparison. Not sure how these guys became airline of the year a few years ago.
