No delivery/No contact

I bought a Pierre Cardin Queen sized duvet set online on Sunday 26th November. I was told, after paying, that I'd soon receive an email with tracking details and confirmation of my order. It has been 5 days and I still have not received such an email. When I emailed a complaint to them asking where my product was and why they had not contacted me, but easily taken money out of my account, I got an automated response saying that someone will be in contact within 48 hours. Well, 48 hours have passed and no one has contacted me. Furthermore, when I try phoning the help line, no one picks up. It just rings and rings. I have no idea what I am supposed to do but I refuse to just let my money disappear.
