Exceptional poor service

I currently have 5 vehicle under cover with the Business side of 1st For Woman. I just received a call from Khaya Skosana to inform me that after careful consideration, they cannot cover the LM 2000 Man truck. I have 30 days to seek other cover. This truck has under cover for 10 months and we have never lodged a claim to hamper the risk factor. This truck also has a tracker and back up monitor that was installed by our choice to further minimize the risk. I told the agent that I am not happy and request a call back from management regarding the matter, which he promised to action. Within half hour, I received a cancellation letter and updated revised cover schedule without a manager calling me. This is exceptional poor service, as the company is happy to receive a monthly premium.
