Non delivery and no feedback

I ordered a gazebo via groupon on 27 November 2015.. After some time had passed i phoned groupon to enquire when the gazebo will be delivered. I was given a waybill number. On 10 December 2015 i received a call from the Courier company to check the delivery address. On 14 Decemer 2015 I was advised that my order was despatched. It is now the 4th of January 2016 and after numerous calls made on a daily basis to churchills with the promise they will get back to me, which they have not, i am still waiting.
