After you file

I have a complete status, called the number given and entered the extension given, the man told me there is no way to know what my outcome is, there is no record of a letter being mailed or a check and it can take a year to get a final decision, im so confused bc no where on the internet does it say it can take a year......should i call back? is it worth my time? I mean, I need the extra money, but i was on hold for over an hour....... how long realistically until i should receive and outcome in the mail? im assuming if its denied, I will receive a letter explaining why, wouldnt I?
