lumpy couches and no feedback

I bought a lounge suite which was on display .i was told its the last of its kind .i insisted that the sales person check and he said it's the Last one. A few weeks later I called them as the cushions were lumpy and dips on the sides. i was told they would get back to me .if we did not call they did not bother .at the same time as my complaint the lounge suite resurfaced under a new name.i asked if they would replace it as it is still new and I was told that it was discontinued.everytime we called to follow up they were waiting for head office to respond i was eventually told to bring my cushions and swop it for the new ones.not my job!! And someone else will be getting my lumpy couches.i am dissapointed with the service and to date have not heard another word.
