Poor responding, when parcel goes missing

I am a new customer at takealot, only been buying from them the last month. I spent more than R10000,00 in this time on various orders. There service is great when all goes well. For one of my orders, I received a sms Friday the 29 May, saying my order is out for delivery and will be delivered before 5:00PM. Parcel was not delivered, Monday I tried phoning Takealot, service was not available, and voice message said I should send a email. I sent a email complaining when I track my parcel, its says out for delivery and was last updated the 27 May. I received an email the saying my parcel was lost in transit, this was 3June. I had asked a couple of questions, when can I expect a replacement, which courier was responsible. Didnt get a reply, it just felt I could try to find out where my parcel was, as it had been given to a 3rd party, it was close to my adress, it would have been nice to have. I also asked if someone from takealot could give me a ring, which also did not happen. This made me an very unhappy new client. Regards Geoff
