bad service/poor customer service

went in at sterns today at hemmingways I was treated badly by the 2 african sales ladies in the store. I went to exchange earrings that were bought fr me as I was having problems closing them. I did not wear them the lady said I should choose the ones I want afta 15 min of waiting the otha 1 cane out and said they do not exchange earrings so I asked were does it say that cause at the back of the slip it doesn say so the ladies didn answer me only afta 10 min they gave me this little paper that says earrings are not returned. my main concern is if these ladies continue with this rudeness sterns will lose customers. they do not know how to assist customers. im unhappy n dont even like these earrings anymore. never again will you see me at sterns. poor customer service. \our long term relationship with you is very important to us". this line is written on the slip but the people in the shop are no displaying that.
