OUTSURANCE ISSUING "UPDATED" POLICIES WITHOUT MUTUAL AGREEMENT AND YOUR CONSENT

I noticed that my total annual premium had increased by a whopping R300 and I called to see if we could reduce the amount especially since two cars are going into storage. I got really frustrated with the agent and wanted to end the conversation as she wanted to up the premium by R 200 on one of the vehicles as I suggested changing the primary driver. When I said I would withdraw that vehicle altogether from the account she said she would call me back in 20 minutes when I had calmed down to resume the conversation. She called back during a Loadshedding and I did not have access to my computer and asked her to call me the following day. She mumbled something about having spoken to the Actuarial Department but I could not hear her clearly and asked that she call me the following day. Next thing I find an updated policy in my inbox and I am now paying an extra R 500 a month on my total policy ! I did not agree to any changes in my policy and I had not yet discussed the adjustments that needed to be made on the rest of the policy ? which means that outsurance will just deduct that amount from my account come 1 November. I now need to waste a whole lot more time on the phone to correct this assumption not to mention that the customers interests and needs are not taken into account at all. I subsequently got a quote from another company on the Vehicle in question for R 475 less ! (from R783.00 to R 308.00) If Outsurance can overcharge me on one Vehicle I cannot imagine what they are doing on the rest of my account. I am cancelling my entire contract after 15 years with Outsurance . They don't deserve my business or my loyalty.
