Three time failure to satisfy us

My husband bought a two piece lounge suite in September within a week the three sitter was sagging then we called the store and they came to collect it then we waited four weeks without any feedback from the shop so then we decided to visit the shop to check what could be a problem then we were told that their telephone lines were not working then fine after a week they delivered another coach but damaged on the wood trim and dirty because its a cream to light beige colour then my husband called the sales lady and she said she will order another set then fine so she did but then when we sit on the three sitter it makes funny noise like something is broken inside my husband and I spend our savings money hoping we will get quality but instead we get second hand lounge suite and this thing is tiring three time and still we Dont get what we paid for and we need the suit we paid 16 000 thousand rand I feel if they can't deliver to my needs then give me a refund orf please give me the what I paid for if I wanted second hand I could have went to a shop shop I'm gutted because I can't host people I'm ashamed <br>
