Online delivery service from Makro Wonderboom sucks!

Hi, I made an online purchase from Makro (Wonderboom branch). I paid the delivery fee and the standard time is 7-10 days. Prior to the 10 day expiry I called their contact centre twice in which I was informed someone (their team leader) will get back to me regarding my delivery. I was concerned that the 10 day period was up and I was to go on leave and the delivery address was my work address. No one got back to me nor explained I should update my address online. Long story short about 15 days later I called Makro contact centre and the consultant jumped down my throat telling me I should have changed the address. She then told me I should give the courier guys the new address which I did and he rep**** saying someone will call me. A few days later I get another call telling me my delivery is on its way I then gave the woman my home address which she gladly said is no problem. The next day I get a message saying my delivery is on it's way (Sat. 22nd Dec 2018). I even updated my address online and to date my delivery has not reached me! I made the purchase on the 28th Nov 2018. This is now one month!
