NON DELIVERY OF ON LINE PURCHASE

I ordered an expensive product on their daily special offers on the 13 December with the hope that I may get as close to Christmas as possible.... It is now the 6th January and I have still not received my purchase. I have sent three emails asking for feedback as I am now desperate for my order but no update. I have tried phoning the call centre on 031 and there is ZERO response, phone just rings. I am so extremely disappointed in the service. I just want my product or my money back but to just ignore my emails and no answering telephones is just unacceptable as well as the delivery time...

Waiting for an urgent response.

Thanks. Tanya.
