Hi Kerry...
As silly as this sounds, I think the person you spoke to at the insurance company basically didn't know wha the was talking about... told you you'd have to pay through the nose, and then when he got off the phone, went to check with his boss and got told that he was talking out of his schvinkter. Rather than admit that he was wrong and look stupid to you down the phone, he's made it out like they are doing you some massive favour, when in reality.... they aren't.
Cancelling a policy mid term in 9/10 cases results in a standard admin charge, as said above of like £30. A full refund pro rata then ensues, providing no claims are made, you return your certificate of insurance, and job done.
I genuinley think he got it wrong and then tried to cover it up by trying to baffle you...which he succeeded with. lol.
I don't think you have any need to worry at all.
