Terrible customer service

Terrible terrible service from Browns head office and the so called “master jeweller”. My finance’s engagement ring was bought 9 months ago and one of the claws holding the diamond has moved. It was taken to browns in Brooklyn and the lady was helpful and said it would be sent away for assessment. The assessment took 10 days and they came back and said the ring will be fixed free of charge! It was returned today after 3 weeks at the head office and the only thing that changed was that it was cleaned and polished. The claws were not at all repaired. Nothing was done except a cleaning. I wish I had never purchased the ring from Browns’s as this is a common occurrence.
