mislead by a consultant

I received a call from a credit life consultant a few months ago she encouraged me to take out a credit life cover over my credit card with Absa when I asked about the figure she told me it would be 3 Rand each month and it would be included into the credit card I asked over and over again are you certain it's only 3 rand and she said yes so I went ahead and took up the policy only to find now 4 months later after checking my statement each month I'm being billed more than 100 rand she didn't tell me that it was R 3 . 25 cents per thousand that you owe.I have sent through a letter to cancel I have also call the call centre and spoken to 2consultants asking for a full refund as this was not my problem it was not my mistake the consultant needs to be held responsible I need feedback as soon as possible and want this resolved .I have queried this on the 20th of February and I'm still waiting for a response and money has still been taken out from my credit card each and every month
