Disgusting after sale service and warranty claim

After purchasing a bodyglove tablet cover, then it breaking within 3 months, i fuming. Then i tried to contact bodyglove USA... no response. Then i tried to get hold of local distributor... no response. Then my third and final option was to go bad to vodacom with my purchase slip. The sales assistant tried to tell me of a warranty period which was considerably less than stated on the packaging, but she still tried to argue with me. I then got the managers email address which i forwarded everything to him, but still got no response. So what now, i have spent almost R500 to buy the cover, then had to go buy another cover of almost another R500, which i have been using and been extremely happy with. The branch in question is the Canal Walk branch situated in Cape Town. I would like the sales and marketing director to respond to this directly, with a solution. I have my paperwork and packaging, and to be fully refunded.
