Bad Service - Not Willing to assist

I went to the Grove to return a ring which was previously sent for a resize and where it was joint currently detached ,the resize was done in March 2015 and still under warranty but however when I got to the store I was assisted by a lady who refused to give out her name. Initialy the resize was done at American Swiss Menlyn store. Fistly when i tried to explain my situation the lady went out to say I should drive back to Menlyn,my question to her was if I stayed at Cape town for example does it mean I have to fly back to Pretoria, on the spot her colleague by the name of \Beauty"stepped in to assist . I only got to hear her name when she phoned menlyn asking them to forward the receipt for the resize done when the person who picked up at the other side asked for her name . Note neither of this ladies were wearing name badges .When I asked to see the manager the lady who refused to give out her name shouted to say \"" I am the manager\"".I walked out the store leaving my partner at the counter to clear my mind next thing she rolled the door down 30 minutes earlier. When I asked \""Beauty\"" for her colleagues name she responded by saying \""Ask her yourself\"" by the time she was already gone"""
