False Advertising

I have been contemplating purchasing a new cellphone. When i decided to buy a new one i went to a TFG store. I have been reading there cellphone catalogue on which is the most suitable handset. When i went into the store, i knew exactly what i wanted to buy as per the catalogue. I went to Sterns in the Promenade Mall to purchase the SAMSUNG GALAXY STAR 2 POCKET NEO DEAL.The Samsung has been advertised as a 3G , but discovered that it was not what was advertised , i went back to the store to report this. All that the consultant as well as a headoffice representative told me was , it was a miss print and the the phone is not a 3G but a 2G and apologised for the error. They also said that they do not do refunds or exchanges . I am really disturbed re this matter , as i am paying for a feature that was falsely advertised in the catologue as well as there website.This tell me that i need to take my future business somewhere else, as i can not trust the TFG advertising and with this error, TFG is not planning on correcting the matter , but only to apologize.Very disgusted though , that after being a loyal customer to the TFG group , it has come down to this. No help what so ever
