Terrible Service and Poor Quality Goods

I bought a lounge suite in the beginning of Nov 2015. About 2 week later i saw that 2 of the couches backrest were gone in. i called into the store and they sent someone to my house around the 27th Nov, he said that they not damaged and needed to be puffed up. What nonsense when you can clearly see that the couch is gone in. We have made many calls to the store and sent pictures and have got many empty promises from the sales guy and the manager. We now do not want this suite anymore and want a refund and no one ever returns calls. the service is terrible from this store and i tried getting numbers for the head office and the another sales guy tells me he cannot give it to me? we spent 26k on a suite and this is the horrible quality we get .... and the worst service Disappointing!!!!
