I think a lot of ppl in pimd do not know how to count year. If you started 2013 or after September 2012 there's no way you get 2 years achievement. And if you started December 2011, you need to wait till december 2014 to get your 3 years achievement.
I emailed support and asked for my date started playing and they couldn't give it to me! They said to look in App Store and it didn't have it either. This account is almost a year old and I'd love to know exactly when it reaches a year.
Hey guys, Having reviewed countless emails asking to confirm the achievement date, we are sure the achievement was given out correctly. All cases reviewed were simply that accounts were near their anniversaries, but not quite there yet.
