Experian AKA credit reporting Ripped me off after I cancelled my dollar subscription Nationwide

I signed up for my credit report from experian which cost me One dollar after 7days you will be charged 24.95 a month! I had cancelled before the 7 days and I had also filed a dispute because all credit reporting agencies are reporting inaccurate information for years if you don't catch it they just let it go! Now I have proof from my credit collection agency that they had marked my account as paid in full back in 2010 and they had reported it to all the agencies, I have just now checked my credit report and they still have not removed the inaccurate information! I now have it in writing from the credit collection agency that my account is paid in full and that all copies will be sent to all credit reporting agencies. How long or how much more will I have to pay to get my credit report fixed!
