No repairs for the screen

I bought a Vodacom Tab 3G in November 2014 and the screen broke 2 weeks later. I know that on the screen you usually don't have a guarantee but when I went back with it to Vodacom they just said it was too cheap to fix. Then I went to 3 diffent cellphone repair shops and they said I can just as well buy a new one. It doesn't make any sense. Why would a company bring out a product and there is no spares for it. I just want it fixed. I only used it for 2 weeks. And even now in the new year there is no spares for it.R999 wasted on something worthless.
