Hachette partworks doesn't deliver

I want to warn people not to subscribe to Big and Little crochet. They have been debiting my account for the last 3 months,but have only received 1 parcel( issue 1). They don't supply tracking numbers either. Contacting them doesnt help. I have phoned and emailed to get a refund,but nothing is done about this matter. They lure new subscribers by offering free gifts,but then nothing gets delivered. THIS IS UNACCEPTABLE. PLEASE REFUND MY MONEY.
