Pathetic service from Charity @ Fourways

I am shocked and disgusted at the service i keep receiving from the Fourways mall staff. I purchased a ring from this store and the stone fell off 3 months later, i went in to enquire about the repairs and there were 2 ladies there, Charity was busy with another customer and she asked me to go to the other lady, upon me telling the other lady that i dont have my card with me, she acted dom like she couldnt help me, she then told the story to charity who then asked me what i wanted? Yet the lady explained everything to her in front of me, i informed charity that the lady just explained it to her and i dont see why i should explain it as well and she abruptly informed me that she doesnt see a problem with me telling it to her again, i told her i didnt have time to argue and she stopped assisting me, I asked for the store manager and was told she would only be there tomorrow and was given the store number to call. i asked for a cell and was informed the person doesnt have 1. Why is your after service so poor? why do you employee people of such calibre to work at a busy mall. Apart from that i wanted to make another purchase as the ring i bought is almost paid up, but after this i will cancel my account with you and never support you again.
