Dishonesty

I have sent and email on the 23rd of May to cancel an insurance with them because I have found a cheaper provider. They rep**** to my email with case number ***3 and promised that a consultant will call me. I waited until I ran out of patience, I then called them, I was transfered to the cancelation Team and waited for over 4 minutes until I cut the call. They normally deduct on the 28th but because I want to cancel they deducted on the 26th. Now I cant get hold of them, my new provider has to deduct on the 28th, there's no money in my account. I want a refund immediately. I saw most of their former clients complaining about the same thing.
