Pineapple insurance is refusing to refund my money they debited after I stopped the insurance during the cool off period

Pineapple insurance is refusing to refund my money they debited after I stopped the insurance during the cool off period. In fact it was the same day. After cancelling my polio they are now just ignoring all my messages to the. Do not use the *****s. I shudder to think what a claim procedure would have been like had I stayed with them. I will see if the respond in the next few days then go to the ombudsman.
