Broken vaccuum cleaner

I have purchased the Genesis vacuum cleaner on the 3/11/2015 at Game Stores Kenilworth Centre Cape Town at the price of R749.00. After just 2 months the vacuum cleaner heated up, and just stopped working. I only use the vacuum to clean 1 middle sized mat and a smaller rug. (i did not even try to use it harshly as shown on the ads ) I have contacted the Game Store (VERIMARK) enquiring about returning the vacuum. They have advised they send it away for repairs which takes about 21 days. I have also contacted VERIMARK head office they have advised the same. My complaint and concern is, i have paid for the vacuum and find it unfair for it to be sent in for repairs (it is brand new!!) i did NOT purchase a second hand vacuum. I now have to be without a vacuum for up to 3 weeks which was not my fault and i can guarantee it is a manufacturer's fault and no fault of mine. I am disappointed in the name VERIMARK as i have purchased quite a few goods from them over the years. I feel they are not living up to their name. I do not want my vacuum in for repairs i would like a new vacuum (2 months is still considered as brand new). Thank you
