Incomplete delivery

I placed an order on 17 November 2015 for 2 x exquisite base sets (which are to come with free single bed mattresses). In December I received 1x full base set and 1 mattress without a base. Home choice calls me every single day for payment yet they still have not delivered my full order, it is now 20 April 2016 and no one can tell me anything about the rest of my order which I' being barked at about every single day for not paying for. I am deeply disappointed by this and will never purchase from them again. Not even one consultant tries to help when I tell them my order is still incomplete 5 months later. I'm truly disappointed.
