Scamming company!! I put a deposit down for the insurance with the promise the insurance would start straight away and the documents would be sent. No documents were sent and had a text saying I would not be insured until I spoke to them on the phone, so rang and could not get through. Due to being away, could not continue to hold, so took out a new policy else where. When I eventually contacted them, they told me I was not me so they could not cancel the policy, and they started it without me knowing. They are currently trying to force more money out of me, and am not looking like I will receive a refund!!!
