I've had an insurance policy with an insurance company for just over 6 months, I've recently been looking at getting a new car and decided to buy one, Before I bought it I checked online how much it would cost to swap my insurance over to the new car (the insurance company let you swap insurance over online and calculate the extra amount you owe depending on engine size, etc automatically) I checked and it said it would cost an extra £36 for the rest of the year.
I purchased the car today and checked again and it said "we cannot insure you for this car", I spoke to them and they said there is nothing they can do.
I have proof (screenshot) that it quoted £36 less than 3 days ago but now they can't insure me on the car.
My question is - Can I take legal action against the insurance company as I wouldn't've purchased the car unless they had said I can swap the insurance over (which they did)?
