Very Disppointed policy UNQA*** policy cancelled without my consent

I have an insurance cover with Oakhurst, Policy Number UNQA ********** and a courtesy car cover which i pay separately from my insurance also with Oakhurst of R139+, i received a letter from Bianca saying my insurance policy will increase from R800+ to R1100+, I send her an email on the 03.11.2018 regarding the increase and she did not respond, on the 07.02.2019 i called her and asked her about the increase and she said Mandisa will call me regarding that, Mandisa called and said i will receive a discount, i will pay R900+ instead of R1100+, I asked her will my benefits change she said no they will not change, i did not even speak to Mandisa about the courtesy car cover of R139+ to my surprise today i receive a letter from Bianca saying my Plantinum cover was cancelled, i called and asked what is that and she said that it is the vehicle hire of R139, how can they cancel the cover without my consent, and when i spoke to Mandisa why didn't she tell me that we are reducing your cover and cancelling the other, i would not have agreed to that, because how will i get to work without a car, so it means she was lying about the discount, the discount is them cancelling something i did not even ask them to cancel, i want Mandisa and Bianca to listen to the call and tell me where in the conversation did i ask her to cancel the vehicle hire cover.When i spoke to Mandisa yesterday i thought the service at Oakhurst insurance has improved and to only to find out i was wrong, because this time the agent just cancels policies without being asked by the client, i would never recommend anyone to join Oakhurst and the reason I'm still a client of theirs is because i do not want to go through the 6 months waiting period with other insurance companies.
