Joined Edgars Policy without me agreeing to it

I went shopping at Edgars in Centurion and was approached one of the consultants named Shela. She then asked if she can explain to me the policies that they offer. I gave her the opportunity to do that and she said she is going to give me the opportunity to think about it for a week and if I am interested in joining I should then call in and it will be easy for me to join. What she needed to do when she explained was to record my details by me signing the pad. I asked to make sure this does not make me join the policies and she assured me it does not. The following day I received SMSes welcoming to the policies. I called immediately to cancel the policies and explained what happened. They promised to cancel the policies and it wasn't then as I shortly received emails welcoming me. I called again and requested them to please cancel and got a rude person who told me there was no policies on my name and they were cancelled. To my surprise the policies are now appearing on my statement. I am not prepared to pay for something I did not agree on demand a reversal.
