Getting Cartel Coins When I'm Not Subscribed

Hi,

So I'm not really sure where I can post this, so hoping I can actually get a response to this problem here.

So it's been about 1-2 years since I've played SWToR, I currently have it uninstalled, however in the course of since I last played I've been receiving emails every month notifying me that I've received my monthly complementary cartel coins. I assumed at first it was due to having a security key registered. Reading the email however shows that I've been getting 500 per month. I further assumed it was simply a mistake, and that they were using the same auto email for the security key thing, which gives 100 coins every month, regardless of if you're subbed or not. I decided to just double check my account today and noticed I've been receiving the 100 coins from the security key and 500 from a sub every month, and my current cartel coin balance is sitting at around 10k. Hopefully you can see the problem here. I'm not sure if this is intentional or not, but I don't wanna risk losing my account due to this mistake.

TLDR: Basically I've been getting 500 cartel coins every month for at least a year+ even though I'm not subscribed and want to know what's going on. I'd rather not get banned over some error on BioWare's end.
