Poor Quality

I recently bought 2 pairs of earrings at American Swiss and on both occasions had to take it back to the store due to poor quality. The one pair which I took back to Rosebank the lady repaired it and gave it back to me. The other pair which I also bought at Rosebank went to the Cresta branch as I asked the lady if this can be fixed at their store, she was quite helpful and said you can take it to any american swiss store. I then took it to the cresta branch and the black lady was quite agitated and then I was not happy & was quite rude and told me that i should then go back to the rosebank branch. The issue I am finding hard to deal with is that customers cannot return earrings and the retailer should then ensure that the goods are 100% good quality then we don't need to come back to the store. When we buy items from them we expect this quality. I am very disappointed and feel the quality should be addressed as the things are not cheap or free.
