Poor Customer Service and Very mean

Poor Customer Service, from the sales Agent , My sister went to buy a TV when she got home the TV didn't fit in the stand so she had to return it to the shop and get a smaller one , I had to drive her there , they took roughly 30 minutes inside. Ok furniture I needed to pee I didn't have coins so I went inside the shop and explained that I had an urgent need to use the wash room I didn't have coins ,the Agent Nelly told me that she wasn't allowed to give customers the toilet I have to wait till I got home, Theku Plaza osizweni is very far from where I live, she is very mean
