Cancelling Subscription - did not want full years subscription

HI, Can you please give me a refund on order number
#137781080800 as I did not want the subscription to continue. I need this refund asap as did not get any notice that the subscription was to continue.

Thanks

Thanks but I have tried that and it after selecting all the options just ask you to call. I am in UK not US and not prepared to call US number due to cost.
