Money debited twice without my consent

I was approached by one of their agents that they are collecting Data to see if people would be interested if they open an policy at mall of Tembisa ,he took my details, when I asked he said they will call me to confirm if I want the policy BUT this morning I woke up to a deduction from the on my bank account from last month on the 25th of April. Apparently this is what they do to people becausewhen I was checking a lot of people have the same experience as me. When you call them their consultants drop the call. I don't even know which policy did I sign up with them cause that guy did everything on their tablet making me believe it was just to give evidence that people will be interested. It is just unfortunate that I can't attach proof here of my conversation with the guy. confirming that they were suppose to call me to confirm before deducting my account. I also have screenshots of people with the same problem with Clientele.
