Thank you for signing up for a Premium Stats account. When you sign up for a Premium Twitter Stats account we start recording your Pro Twitter data. As mentioned on your profile page and on the page you signed up with, we only have been tracking @Banco24Horas since February 7, 2012.
Which means you can't go back to 01/01/2012 because Twitter Counter cannot display statistics for data that was not recorded.
However, from March 11th, 2013 we will store all the information we're able to get, so in a couple of months we have data from the start of the subscription.
If you require further information about your Premium account, please email us at firstname.lastname@example.org
