experian Ripped me off money for a free trial report Nationwide

I ordered a 7 day free trial from Experian and cancelled before it ran out so I would not be charged. I was charged anyways so I called them to complain and they said I never cancelled so the charge was legit but they could refund me 9.95 of the 21.95 that I was charged.

I continued to argue with them that they was wrong that I did cancel and if it was showing up in their computer than there is a problem with their automated system. After several minutes the operator then stated that I did indeed cancel but it was after the trial period so the charge was legit which is also incorrect. 

I said just give me the 9.95 that you said I can be refunded then because I was tired of argueing. She then said that she never offered me 9.95. I said yes you did and don't forget this call is recorded therefore you are on record offering it to me. She said well I did but I'm not giving it to you because you didnt cancel in time. Experian is a complete ripoff and offers people a free trial knowing that they are going to charge them anyway! I want my money back!!!!
