Why is it so hard for HR to call me back for an interview?!

I must be doing something real wrong yes. I remember sending a resume to the National Gas Company sometime this year. They mailed me back saying they didn't have any positions available but they would keep me on file. Low and behold, I hear that new graduates are being called in for IT interviews. I am amazed, disappointed, appalled at this. Life just seems to be full of bad luck for me. Now I am frustrated... I wish I knew what to fix. This is another reason why HR gets a bad name. For God sakes what is going on!
