******** deductions after expiry of contract

Around the 14/15 January 2014 i took out a 1 year subscription online with Transunion and paid R180.00 once off. which was meant to expire in Jan 2015. In Jan 2015 i indeed received an email from them reminding me that my subscription would expire on the 15th Jan and they encouraged me to visit their website to renew it. I ignored that as i was not interested in renewing it. To my surprise i noticed at the end of July that they unilateraly renewed my subscription in January 2015 after it expired and converted it to a monthly R40.00 subscription. On August 21 i sent them an email demanding refund and only received and automated reciept of email acknowledgement, nothing more.<br> Below is the email i received from Transunion on the 10th January:<br> Dear winboy, <br> Protecting your credit information is vital. A quick reminder from TransUnion that your <br> subscription to Credit Report Plus Alerts is expiring on 1/15/2015 12:00:00 AM<br> <br> Visit us on [URL Removed] to renew your subscription<br> <br> Kind Regards <br> <br> TransUnion Interactive Team <br> Call Centre: ***<br> [URL Removed] <br> <br> I demand a refund of all monies due to me by Transunion and immediate cancellation thereof.
