Return/exchange refusal

Cell C customer service refused to let the shop attendant help me in exchanging my handset. The handset was received on 30 January 2015, and I tried to have it exchanged for a different handset on 1 February 2015. The reason I wanted to exchange the handset, is because I am not satisfied with the overall quality of the handset. I was under the impression that with the new consumer act, that companies would deliver better service. I was WRONG!! Cell C, maybe you should take some pointers from Vodacom on how to treat customers! I regret ever leaving Vodacom.
