Watercrest Mall - Masters at passing the Buck

I have being experiencing issues with a brand new Samsung cell phone taken on contract from the MTN watercrest mall waterfall dealer. Since the very beginning , I have being complaining that the phone is not functioning correctly. Its almost 6 months now and every time I walk into the store , they do not do anything but are able to brush me off. I had being promised that a Samsung rep will contact me which never happened. As a last resort . I went to Samsung directly and was advised that the phone can be repaired but it was not advisable because the phone is too new. I was also advised by Samsung that MTN watercrest Mall is obligated under the consumer act to replace the phone because of the fault because its still less than 6 months old. I went back to the store and was advised that unless I have the original packaging ,they cannot assist me. I have all the accessories and cannot believe that they can use the card board box that the phone came in as an excuse not to assist. Who in this day and age keeps packaging that is almost 6 months old .I dont have a separate storage room where I store old boxes.
