Poor service delivery

I ordered a TV box on the 29th of March and on the and on the 31st of March and the days following I received SMS' that my order was out for delivery on those days but I still haven't received it. I still received a message that my order was going to come yesterday but it still didn't. This is so disappointing and I'm beyond frustrated!!!! I AM LIVID. I would like a clear explanation as to why this has gone on for so long. Who still takes years to deliver???? An order that was placed on the 29th of March and tomorrow marks almost 2 weeks of being mislead about this order. This company is failing dismally at customer service. I had to call today not even 30 minutes ago and the lady assisting me had no answers for me. She was very dismissive and kept putting the blame on the Bellville warehouse and not telling me what's to happen from now. I am the one bringing a complaint forward but not only was she dismissive she was also getting upset at me when I was the one complaining. What kind of customer service is that?!!!
