Bad Service

MY ISSUE IS THAT I have been making calls for the past three weeks no one has bothered to help me only one consultant pearl at least tried to assist , I have laying complaint on the same bag firstly they said they packed the bag and i kept on following up mind you I'm using my own airtime to call their online shop , today i was fed i made a call straight to Hemmingway's Foschini spoke to Ferozah now she tells me the bag was never packed they don't have stock and but they sent two invoices pretending as if they were two bags when i insisted acted surprised . now they only tell the truth that they don't have stock their system does recognize that the stock is finished and they asking me to go to the nearest Foschini so that they can credit me , so now i have to spend more to get my money back . no one has bothered to call me and apologies or at least give me feedback I had to do the digging on my own. I'm beyond upset I'm angry . why advertise stock you don't have. why not contact when when they have all my details three weeks following on one issue
