Happened for me as well. It seems the entire SMS Refill window is bugged. There's usually several rows of flags, but now there's just one. Sweden's isn't even there, which I noticed after I purchased a code, since I just used the SMS saved in my phone.
I expect to at least be refunded my code or added the amount of Gelats that the Swedish code is supposed to do (Think it's 180 or similar, I know I have to buy two for a month of Gold).
