Poor Service !!!

I think i have really had it with the poor service of homecoice i ordered a bed in February which was delivered on the 21st of Feb 2015 the driver who delivered it delivered the wrong bed i assume because the invoice attached belongs to someone else. The driver also didn't give me THE OPTION to assemble the bed of which i did myself. I phoned homechoice the 24th to advice that something is wrong with the bed they promised that someone will come and have a look at it or they will replace it i phoned in a few days after and advised that they must come and collect it because the quality of the bed is not so good i would rather order another bed i told them to please speed up the process because i really need a bed i am still waiting for some sort of communication from them and seeing that i need a bed i have been using the bed so the state the bad is in is actually horriible if that is the quality they sell then we as the customers will have to buy a bed every 4 months. And eventually thats IF they come to get the bed they will give me stories of the condition after i called how many times to tell them to come and get it how do i go about this ???
