Foschini TFG online shopping *****

Can someone please assist me. I ordered items online over four weeks ago for R1880 and have still not received them. I have been back and forth via email with the customer support who advised me my parcel was at the local post office, after visiting the post office to find nothing there, I contacted them again requesting the curriers name and contact number in which they just ignored my request to give me the information. All they responded was sorry for the inconvenience can we offer you a 10% refund. 10%? I cannot believe it. Where is my items, who can I call, why are they not trying to assist in locating my items? The customer service is not trained as they do not even respond with correct spelling or grammar, absolutely no email etiquette. How is this possible for such a huge company to not even be able to provide a customer with a contact number? Basically they have said we can’t help you and will give you 10% as compensation
