Dishonest broker advice

I have been trying to cancel my King Price policy for about 2 weeks now and Insurance Supermarket as the broker has been making this extremely difficult by not being forth coming and in fact lying to me on a recorded call by telling me that any insurance policy for a vehicle should be in the financed person's name and can't be part of a separate policy. This is condescending and aggravates me even more with this whole process.

Another problem I have is that I did not ask for his financial advise on any occasion but he insisted on giving it to me and continuously talking over me and not allowing me sufficient time to talk and explain to him why I'm not interested in maintaining the policy.

Finally the broker explicitly told King Price that I will be keeping my policy even though I told him that I am not keeping the policy active so he **** to me and **** to them and at the end of the day I'm the one paying for his dishonesty, I am very close to taking this further and getting my lawyers involved as I feel that openly lying to a client is unacceptable and then furthermore lying to King Price with regards to the status of my policy is ********* and costs me money not Insurance Supermarket.

Can someone please assist me with cancelling my policy as soon as possible?
