www.starnow.co.uk / They haven't returned my money back

I signed up for the website www.starnow.co.uk, but I haven’t used it a lot. I paid for the membership, but after some time I decided to cancel it. I contacted the rep and asked to stop the membership and return money back. The rep replied that I would get money within 2-5 days, but it was fake promises. I haven’t got my money back. Please, help me to solve the problem and post comments about this website.
