beware when buying online

I have ordered products with makro online on the 22nd of November. Upon check out it indicates that there is stock available and that I had to complete check out, payment was done immediately. They indicate that it will take 3 to 5 days for pick up. on the 28th of November it shows that my order is still in process. I queried with the online service centre. I received a e mail back stating that they will sent query to relevant department, and that they will be in contact soon. No phone call or email received from them. I contacted the online service department, just to be told that there is no stock available, the lady Mbali rep**** that she will phone me back with an answer on the 4th of December, but again, no phone call received. Again on the 5th of December did I placed an complaint on Makro's Online service department. As yet no response received from them. My items still shows in process and still no correspondence received from them. They got their payment immediately but I have to wait for my products.
