Billing my account for a year after i cancelled the service

<p> </p> <p>I cancelled a service from Transunion in April 2015, since then i have cancelled the Service another 2 times and i have been billed every month Since April 2015, this is a charge of R40 on top of the same service i am paying R20 for as this was a Limited offer which i signed up for.</p> <p>I have sent Transunion messages and called about getting my money back and all i get back is i will get my manager to call you.</p> <p>this has happened every time that i have to call these people can get the SAME service cancelled again and again. Transunion are *****ing my money out of my account and will tell me the service is an auto renewable service and asked if i want to cancel it, this was the day after i had called to cancel the service a 3rd time.</p> <p>just so you know the service i am talking about is the Monthly SMS alerts on any activity on my name. </p> <p>They have ****** over R400 out of my account and no one will even contact me to get my money paid back to me. </p>
