RAC comprehensive Cover for 11 months +

Hi, I sold my car in April 2012 but somehow forgot to cancel the RAC auto renew. They have renewed it from Sept.2011 to Sept. 2012. They are not ready to refund it but happy to transfer it to any one else. Its a complete waste for me but it would be worth for any one looking for RAC cover. because its quite discounted and can be continued thereafter as well. below is details- Original cost for comprehensive cover - 12 months - approx. 71 GBP It cost me at discounted rate - 38.5 GBP I want to sell for 11 months - 20 GBP Raj 07424548152
