Its a jobby take back world

As a recent graduate from a univeristy with a Bachelor's in Economics as well as a Bachelor's in Gov't & Public Affairs . . . I have been searching for a career and well Today I get a phone call for an interview to become a financial advisor, in which I will leave the companies name out, for the moment anyways. But however, I had also received a rejection letter a month ago from the same company stating they "wished to no longer persue" my resume and application. Thinking, figures, I blew it off and burned with the rest of the trash, until today. I asked why they decided to revisit me? After all I was rejected once, is there noone else? So are they are going to interview those who are not quite up to the expectation of this company? Well apparently, the lady (non-english speaking) decided that after she set up an interview with me, that she would be a take backer, and take back the offer. Fine with me! But later in this day, actually it wasn't even five minutes past, I recieved an email from the exact same lady . . . only to have the emial say and I quote . . . "Thank you for your interest in the Financial Advisor position with "COMPANY WITHHELD". Please hold on to my contact information for future reference. My toll free number is . . . " So I'm confused. How can you offer someone an interview and then take it back and then email them and aske them to hang on to the contact info? After all this, I'm pretty sure my interest in that company is all gone.
