Own expenses for collections/delivery of faulty sm

I bought two Sony smart devices from the FNB dotNet store in Centurion mall and when I asked them what is the process when one of the devices are faulty I was informed that they will collect the device and take it in for repair.<br> Today when I phoned the Smart device center I was informed that I must Take the device to SS cellular in BOKSBURG on MY OWN COST or I can courier the device. Please explain to me how the hell can you expect me to send in a faulty product on my own cost????? what is the warranty for????? I am located in Pretoria! I will not take or courier a faulty product on my expenses!!!!!! This is pathetic!!!!! Arrange for someone to come and pick up the faulty product that you sold me!!!!!
