Subscription Issues 2021 (not steam purchases) bought from swtor.com

Hello,

When trying to buy membership, I've had either of these two errors:

• The EA Billing and management services cannot be accessed at this time, please try again later.
• An error has occurred while trying to process your request. Please, try again later. {0}

Following these steps (https://swtorista.com/articles/swtor-account-cant-subscribe-due-to-maintenance/) led to an interesting chain of events: despite from what I read, my SWTOR account wasn't registered at EA. Perhaps because apparently someone's using a nickname on his/her EA account that is the same as mine for my SWTOR account. So someone is going to get a password reset email...

Step 2 doesn't work, because weirdly only the browser on the computer that I used to register my account works: my private computer on Firefox. Neither Edge nor Chrome work, nor does trying to login on my work-laptop nor my smartphone.

I've never had a situation where a company seems to be actively trying to prevent me paying them money, as if you're supposed to play this game f2p. Really weird.

Anyway, no clue what to do now. Does anyone else know what to do?

My SWTOR account's name is Hemidactylus.
