I just bought a bond for 9m, immediately activated it, and re opened my game launcher. Whenever I log in now it says I have NO MEMBERSHIP!!! WTF! My bond isn't in my inventory anymore since I USED IT!
So that your thread is read by its intended audience, it has relocated here. In the meantime, I recommend that you check out the following support pages.
Check that you might have redeemed the Bond for a 14 day membership passcode.
To check, look in the 'Messages' tab on your account.
If you have received a membership passcode, you just have to use it to get the membership.
