Shockingly poor service and still no delivery

I purchased a Samsung TV on the 27th November 2017 via the online store and payment was processed immediately. I submitted the relevant documentation and received an acknowledgement thereof. Further to that I have had no information regarding the delivery of my item. No response to the email enquiry and no answer on the call centre number. In this day and age with so many competitors available i find it incomprehensible that a business can offer such a poor service. Do not offer the contact details if you cannot even answer a phone or email. As some one in the service industry myself if the company I worked for provided the service I have received from your business we would have to close our doors. I paid and obscene amount of money for the item and i expect deliver asap. My order number is ********** 41 and need a response!!!!
