vodacom refuses to take device back within 6 dsys

I bought it on Wednesday. I was not happy with the android. i went to return it yesterday. three days after purchase.They advised I had to return it to customer care in Gateway. Gateway advised they could not assist I had to return the devise to the shop I bought it at. I went back to the Pavilion who refused to assist. I am appalled at the attitude of Bawa the shop manager and Ozayr the salesman at Pavilion - not at all interested in customer service. their attitude was arrogant and not at all what one would expect from a service provider. how is this treating a customer fairly? what about the consumer protection act?
