Had carrot for 2 years, on the first year I had the audacity to move adress for which I was charged an extra £300 on top of my premium, ordinarily I wouldnt have minded this but they were extremely threatening and told me I only had a week to pay, on the second year (only chose them again because they were the cheapest and I was a little strapped for cash) they told me I had used all my miles, again was given an extremely threatening letter of cancellation unless I paid them more money. Moral of the story here is you get what you pay for, avoid at all costs, especially if a young driver living independently as I was, they will try something to get more money as they know they can make it impossible for you to get insured ever again
