Delivery of damaged lounge suite

On the 24th September 2015, I purchased a lounge suite from Russells at the phoenix Plaza DBN.the lounge suite came with a free carpet. When I asked ****ha the manager for the 10% discount she never gave me the carpet. I was promised delivery at 14:30pm on the 25th September 2015 but I only got delivery at 19:00pm . I had to make several phone calls for delivery. When the lounge suite arrived, I check it up and noticed that ****ha sold me a second hand lounge suite. The legs are damaged with marks.the beading is out and it's faded.I spoke to ****ha and she refused to change it for me but when I purchased it she said to me that if anything wrong, I have 7 days to exchange the lounge suite. She wants me to take my cash back. ****ha and her assistance manager Rozanna came to my house to check the lounge suite. The Rozana asked ****ha to give us a new lounge suite. ****ha refused to exchange the lounge suite. I phoned the JD Group customer care and spoke to Conica. She was so rude to me.I sent emails To Patrick Chester from JD group and phone and asked for him.he's too busy to talk to me or respond to my emails. I made several phone calls to customer care but there is no help.
