After I accepted a quote from them on Friday, they decided to call me today and state an error, which meant my premium would go higher by R300, and I wasn't happy about that. I decided to shop around, and I received a great deal by a different insurer. I emailed my broker what had transpired so she could cancel my policy with kingprice. Their senior consultant gave me a call and tried to offer me a better deal. I didn't save a lot from the deal I had received from their competitors, but because of the agents' good service, I decided to accept the offer.
