I went to Makro Germiston, bought 12 kg Hisense washing machine. Had a problem with it along the way. I took it for repairs, then they said I must get credited for it, where the credit was done. From there I bought other machine. It was on floor at store saying is marked down due to scratches but everything was fine. I didn't have problem with scratches, I took it. They deliver on Saturday afternoon. On Sunday morning when I wanted to wash, I was surprised by leaking of water. Went back to them they come and collect but not bringing the new one as I paid extra for new one.
