I have been a customer for 5 years. When I received my renewal my car insurance had doubled. I have been driving for 30 years and have never had a claim. I called them, and was told they could see why the increase and would get the pricing department to check. When they got back to me I was told there had been a 'mistake' and my quote was £250 too high! If I hadn't queried it i assume they would have happily over charged me. By shopping around i saved nearly £400. The same has happened to two of my colleagues. I wouldn't use them again as I have lost trust. How can an insurance company make mistakes in calculating their premiums?!
