Terrible customer service - the worst service consultants

I signed up for home insurance with this company, via the Nedbank home insurance product offering. The consultant called me, and provided me a quote of R147.12 which I requested a copy of via email. They then subsequently called me later in the day requesting a confirmation of my acceptance of the offer, I then agreed to it only on the basis of the quoted price. I requested the consultant to provide me with confirmation over the phone that all the terms of the contract have been said to me over the phone including the correct premium of R147.12 which she did but to my disappoint, when I received the policy document the premium was R184 and everything else was higher that what was agreed. I then spent an hour on the phone the next day, trying to contact the consultant with one individual from the company hanging up on me when I asked to speak to the consultant Tasneem. Eventually I got to speak to Tasneem and she under the directive of her management told me that it was not her fault and it was a system glitch that could not be solved by anyone. I was told I was quoted a discount price but the price I would pay is now higher and I should just cancel my insurance if I am not happy with paying "an extra R40". It had not even been 24hrs since we had agreed on my quoted premium of R147,12 but now I was already been told that I should cancel my policy for not getting a deduction that was promised me. I was then transferred to the cancellation department where I was told two shocking things, 1) The consultant asked me if he could call me back within the hour despite my urgency in just cancelling the contract as it was due to be deducted that morning of the 22nd of September , 2) That I should accept an offer of approx. R160 which is still higher than my quoted price. This is by far the worst experience I have ever had with any insurance company and I think it is fair for the public to know of the terrible service offered by this company.
