Wow, I submitted mine as soon as I discovered that it didn't work and the next day they announced it. I had a very courteous CS droid contact me to deal with this. I was very pleased by the whole matter. They even let me keep the purchase even though it does me no good. People are really getting up in arms for what amount to about 2 dollars. I admit that I would have been upset if I hadn't gotten my coins back but it was not the end of the world I suppose.
I was annoyed more at the principle of the matter than the value, to be honest.
But they came through for me in the end. I'm sure they will for everyone else too, eventually.
