Makro online waste of time

I've purchased twice from Makros online site and have my first order delivered on time, however my second order hasn't been delivered and upon phoning I then find out that the second order was "supposed" delivered to me which never happened. I was the one that was supposed to be receiving my items as was stated on my order but somehow the order was delivered to another address and signed by an unknown person. I've been in contact with Sifiso from Makros call centre department and I keep getting told that it is getting looked into but it has now been well over a month and there's still no word on what's happening. This is really frustrating as it is pure negligence and I'm still waiting to find out what's going to happen now since I haven't yet received any word from Makro
