Order cancelled, no refund, no communication

On 29 Jan, i placed and paid for an online order. On 30 Jan i receive an email to say "No Stock Order ********** 6". On 1 Feb "Your PnP Online shopping order has been cancelled". I have sent numerous emails, I have tried calling the number on the email that never get's answered, yesterday i sent a Facebook message also with no reply. I don't know what else to do, no one is getting back to me on what's gona happen to my money. I have never been disappointed by PnP until now - really, this is totally disgusting. I WANT MY MONEY BACK NOW!!! It's been almost TWO WEEKS.
