Damaged Goods and Bad Servise

I bought couches at Silverton Bradlows branch from Betty two weeks ago, I waited for more than 3 days for my delivery when I called her last Monday she told me they don't have stock my delivery will come on Wednesday and on Wednesday they wanted to postpone again I refuse and they decided to deliver scratched couches which I suspect them to be a display when I laid a complain Betty accuse me of scratching the lounge suit, so I thing it will be better if you take your suit back and return my money because I bought it cash.
