I am not seriously worried about getting banned. I have an email saying it's 12 months. I just find it really amazing that they would have that kind of mess up with their cards.
Now I am wondering if it was a problem with the activation at the store, or if it was a specific batch of cards or what - if I go back and buy another one, will it also be a year?
How weird is that - it's not that weird when you think about it. Their system is probably running on IIS and SQL Server.
I did some Google searches, could not find it happening anywhere else.
