SA Company Not on time and incomplete Delivery Internet

I ordered last November 20,2016 and they told me they will deliver it door to door. I keep on following it up and old stories they replied always my tracking number when I follow it up to dhl the tracking number was not their tracking number I keep on follow up them in email this last email they already block me and the email said that my email is not monitored, they not answering in the chat and facebook they will only reply once then they will ignore you without talking to you and keep you hanging for hours. when i followup in our local post office i already get it last January 20, 2017 but instead of 5 pcs of items i only received 3 items and not a good quality of what i expected.
