Vacuum cleaner breaks for the second time

I purchased a vacuum in July 2014 for R1199.00. I thought that purchasing a vacuum that costs this much will be of superior quality but unfortunately to my disappointment within two months the vacuum cleaner stops working. That was in September 2014. I took it back to Makro Woodmead and the vacuum cleaner was booked in for repairs. I fetched it in October 2014. It worked for a few weeks then it stops working again. As it was the December period I did not get a chance to go back to Makro Woodmead and also because of our busy schedule I only got a chance to go into the store on the 08/02/2015. When I got to the returns department I asked for a full refund for the vacuum cleaner as I feel that I can't spend almost R1200.00 on a vacuum cleaner only for it to be off no service to me. I was spoken to very rudely and arrogantly by a \manager"called Themba. Who in the first place refused to give me his name. I expected a full refund for me to purchase another vacuum"
