Lewis stores good at taking your money but bad at refunding said money

On the 11th of this month I purchased a lounge suite from Lewis stores Brakpan the 12th they delivered it at my house 3 out of the 4 couches was missing or had damaged feet I contacted the store on the 13th they came to fix it over the weekend I had a chance to sit on the set it was super uncomfortable and it gave off color my pillows went from cream to grey cream so on monday the 16th I contacted the store and said I'm not happy and would like a refund I was informed the manager is not in I must phone back on tuesday they were say cant they exchange it for something else I said no so the manager said they will refund me I asked does he need any thing from me he said no but on contacting them on Wednesday I was informed that I need to go to my bank and get a statement that shows I did pay Lewis I did that and then was told that it will take up to 7 days for my refund!!!! Thursday the 19th my father phones me to tell me that Lewis has come and collected the lounge suite I contacted the manager he said that that is how they do it but still I have no money and now I'm sitting kn the floor the manager says he contacted head office to find out how long it will take for my refund but no one seems to answer his call or email so now I'm without couches and I don't know when I'm getting my money back so I can go get new ones.
