What do I keep paying for?

I have paid twice for services that I don't know exactly what I paid for because I STILL CANNOT EXPORT A PDF FILE.  Can someone at adobe explain what the $29 and the $9 covers because all I want to do is export a file.  Every time I try to do this I get prompted to pay-I pay and still not working.  It would seem to me that the "PAY" link should be attached to the service I am trying to use not another random service.  Are the services intentionally set up this way as to confuse the customer?  When I have called and asked Adobe what is the problem, the response is, "you paid for Adobe Air, or whatever else my 5 different payments have gotten directed to.  Please explain what the SINGLE service that will export a pdf file is called?  I don't need a bunch of random crap-just a  quick link.  Apparently, I also have Adobe Creative Cloud on my account since February that I have never used or activated...this is beyond ridiculous. All I want to do is attach a frigging PDF file to a term paper and send it to a professor.  Still cannot do this since JANUARY 2014 WTF????????
