So, interestingly, I just entered this code. A message popped up saying it was 10 points (just like your original post, not the edited one I quoted). However, my point total didn't change. Then, when I went to look at my point history, it shows this code was good for 5 points, but again, I didn't actually get any points. Weird glitch?
"It appears there may be a technical hiccup with this eGiftcard! I would be happy to send you an email follow-up once this issue is resolved."
Then I asked if I would get a new giftcard issued, and she said "We will be able to provide an update shortly on what will happen!"
