Poor Service

I place an order on the 30th of September for groceries at Qwili Mall in Cape Town waited for my order since , Friday afternoon I got what's app message from someone told me that she received my order for cereals so I must go and collect it there she is not sure when the rest of it will arrived. I ask her to cancel the order as I mentioned that I place delivery order for reason. I sent their customer number or agent message that they must cancel my order and give me refund . Today this afternoon I call then on my shock one of the lady I sent what's to was insulting me while I'm talking to Thuli saying all kinds of insult the fone was on loud speaker so I informed Thuli that I'm the lady she is talking to at the background immediately Thuli removed the fone from speaker and start to apologize on her behalf while explaining myself to Thuli someone else grab the fone and ask me for my order number I never been this humiliated in my life time this is the 5th order I have from them to get the insult because I'm asking for my refund how to I feed my kids today is the 10th of the month the lady with the name Qaphela I believe she is the team leader she even **** straight to me by telling me that they do not do door to door deliveries when I ask her since when she said long time but my latest order with them was in August. Their services is so Pathetic shame they do not have basics of customer service at all . If they can't delivery my order I need my money to buy food somewhere.
