Disappointing

I purchase Studs at sterns in sandton city on the 16th August 2017 on the 20th August 2017 already the Studs stones had fallen off, so i called the shop and i spoke to Thuli who didnt even apologize nor feel remorse for my situation she said and i quote '' Mam we dont do exchange on Studs you can bring the earings for repair but if we find that its not our fault we will not repair them'' Which to me was very sad to hear but i made a decision to not even waste my petrol driving there as if i was treated so cold telephonic ally what are the odds of being given a professional treatment if i am there personally and i dont feel like waiting 3 motnhs for the earings. Never will they get any business from me or anyone i know.
