Debit Order for R570 taken.without consent

I was approached by a salesman at work who told me I could join Mygym without a contract and I gave him my details. The starting date was for January and it was only November so I decided to stop the transaction and think more about it. I contacted Mygym via phone and email and went to their branch in Stoneridge leaving a note for the salesman. Since then all went well untill today \Out of the blue"they have taken money from me. Now I have to take time off work to sort this out ! <br> I shall be reporting on how this is handled from here on"""
