Any time I've had that problem, I've contacted customer service directly and let them know before they find out and think it was done intentionally. It absolutely sounds like you didn't take advantage of bonuses on two accounts, or knowingly take advantage of having two accounts in some other way. I believe they even let me choose which account I wanted to have closed. It's not as uncommon as you might think. I can't guarantee what their reaction will be, but I think it could be worse if you let them find out first.
