Waiting for delivery

I placed an order on [URL Removed] on 20 November 2015 (order #***). Payed by credit card. I received an email on 26 Nov saying that the parcel is on its way. It is now the 14 Dec and I have still not received the parcel. I called the Zando call center on the 2 Dec and was told that the courier had tried to contact me but I had not received any calls. I gave them my husbands number as a second option for the courier and was told that a request was being sent through the courier to deliver. I gave it a week and still no delivery or calls. I then tried calling the call center again but this time I struggled to get through. Phoned on three different days before I got through to a call center agent. When I eventually spoke to a call center agent (14 December) all the agent could say is that the courier company made a note that there is no response when they try to contact me (we have not received any calls)
