POOR SERVICE UNACCEPTABLE

Pep Church street, Shop 3, Joubert St, Johannesburg, 2001. I bought a scented candle that came in a box yesterday upon opening it I found it was broken took it back for exchange today. I’m told they can’t take it because they can’t proof if it was store damage mind you the candle hasn’t been used it’s still in the box. To show it was store damage the broken glass pieces are still place. Then you told there’s no proof who would stack broken glasses piece by piece? I left that candle in the store cause what should I do with a broken candle.
