Expired Discount

[NSXrunner]

I purchased Star Wars: The Old Republic a few months back, but couldn't get it to work. I was happy that I got a refund, as well as what I remember was either a 20% discount off my next game purchase. However I have been too busy to play any games. Now that I was ready to make a purchase my discount code expired. Can I get an new one please?

Regards,
