Misleading Insurance Renewal and Unauthorized Deduction

I was informed by the agent that my current insurance was ending, and I was asked if I wished to continue. I agreed, but after the call, I received a welcome policy from a completely different company. The agent had made it seem like she was from my existing insurance provider. When I contacted my current company, they confirmed that my policy was still active and hadn't been canceled. I then emailed Dotsure to cancel immediately, but they still went ahead and deducted the amount. I had to cancel the transaction with my bank, which charged me R80 for the process."
