Re: SWTOR subscription on Steam question
Regardless of whats used to pay for the time through steam (wallet or CC) the time you pay for you will have access to.
If you stop the subscription, once the time runs out you will need to pay for more but you will keep the time you already paid for.
If you have issues in-game with it showing you as a subscriber you will want to check out our help article here: SW:TOR on Steam
You can also see this highlighted under Steams refund policy, under the renewable subscription section:
Please note that you can cancel an active subscription at any time by going to your account details. Once cancelled, your subscription will no longer automatically renew but you will retain access to the content and benefits of the subscription through the end of your current billing cycle.
Hope this helps!
