Online Order Not Delivered

I've made an order online with Makro on the 28 November 2017. Today is the 11th of December and I still haven't received my goods. I called the Call centre and there is absolutely no answer. I've been sending emails since the first week of December, no answer at all. I went to Makro in Woodmead to try get my order and they told me that Head Office is managing my order and it the order is currently sitting in another location. I want to cancel this order but guess what, when you contact the call centre, no answer!
