Shocking service

I placed an online order for a bed on 27th November 2015 and made immediate payment. I then called the call centre & confirmed that my order & payment was received & was advised that I would be contacted by the courier company to make arrangements for delivery. I called early December & was advised that delivery could take up to 14 days. I received a call on the 11th December to confirm my delivery address but no indication of delivery date. On the 17th December, I called again, only to be advised that my order was returned due to an incorrect address & the courier company failed to contact me. Another order was placed & despatched on the 22nd December. To date, no one can advise where my order is / which courier company is being used / a contact # for the courier company... I find their service utterly shocking. Every time I call, I am told that my request has been escalated. I received another call on 18th January to confirm my address but still no indication of delivery date. The mail sent in the post seems to arrive in my mail box but the delivery of the bed seems impossible.
