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

I was trying to make my 30 day subscription using both card and paypal but always get an error message. I tried this for almost a day, hoping that it was some temporary issue. Then i decided to try the 60 days billed once subscription, which worked. However, after a while i was charged for the 30 days subscription (though i have waited some time between the attempts)  and now i have two subscriptions when i should have only one.
