Unauthorised Debit Order

I picking up an unauthorised debit order by Sage with reference number EC Finanance***1 for the amount of R59.99. I've just called their call centre and was told that I subscribed for a credit record service on the 1st November 2015. I tried explaining to the contact centre agent called Mariam that I have not subscribed for that service nor have I received such a service in the past 2 months. I mean if indeed I had subscribed then my question to her was where is proof of having received/ benefited from such a and she could not give me an answer. She's promised to forward my query to her manager for investigation, but what I really want is my money R59.99x2 to be reversed and this debit order to be stopped IMMEDIATELY.
