Requested quote, got signed up instead

I already have Comprehensive car insurance with Oakhurst. Towards end of August / beginning September, Oakhurst called me to updated all my details. While I was on the phone with them I queried what other insurance products they had on offer, and then asked them to please email the information through to me. Days later I received emails stating that they have signed me up for two extra insurance policies, which I did not ask for - I had asked for information to look through at my leisure. Money has been debited from my account for these two policies. I have since called Oakhurst at least 6 times in the last 2 weeks, either there is no answer, or I leave a message for someone to call me back, but no one has. I have also submitted a 3 complaints on their website. I want these policies cancelled, and I demand my money back. Please go back and listen to the recording. I did not sign up for policies, I was merely requesting information.
