I just wanted to mention swtor's merchant is not associated with steams merchant in any way they are completely separate and unrelated, this is why swtor require proof of purchase for steam purchases as seen in https://answers.ea.com/t5/General-Discussion-Technical/INFO-Steam-Purchase-Not-Working/td-p/9356718/jump-to/first-unread-message
So in effect your issue is with 2 separate and unrelated merchants
I do find that if people have issues purchasing on swtor, my first suggestion is to purchase via paypal on swtor.com, as paypal is again a different merchant
I understand they are separate merchants but the fact remained that when I tried to subscribe to SWTOR through both steam AND the website directly the issue was the same but when I went through the process I described it worked and I have now been able to renew my subscription.
I've been at this for about a week now and have gone through everything I found online and spoken to SWTOR support a few times and was not able to get past this issue until this so I wanted to share it as I have not found this info anywhere else and hopefully if someone else finds themselves with this same infuriating issue then this might help them
For reference I tried to use 3 different bank accounts (1 visa card, 2 mastercards) as well as paypal through both SWTOR and Steam and kept hitting the same issue this was the only thing that has worked so hopefully it will help others
