Poor Service and Lack of Delivery from Makro - Consumer Complaint for MAKRO - Head Office

I made an online purchase from Makro on 26 May 2020. I bought a bathroom tap for R649 plus delivery costs of R52. I received confirmation that my order and been received and was advised that delivery would take 7 to 10 working days. More than a month went past without the delivery of my tap. I had been following up with them, sending endless tweets and complaints on Facebook and I was ignored, then on 25 June 2020 the delivery came. The courier guy did not even let me know that my parcel had finally been delivered. He just dropped it off at the gate and left. The security guard from our complex came to deliver it to me, I am unhappy about this as this displayed unprofessionalism and my parcel could've been stolen had the security guard not delivered it to me. The other issue is that, the incorrect parcel was delivered to me. I ordered and paid for a bathroom tap yet a kitchen tap was delivered to me. I complained once again and Makro, in their defense on Twitter told me that I had made an incorrect order which is a lie because the tap they say I ordered only cost R300 and I paid R701.57 and i can prove this. They promised me 2 weeks ago that somebody will contact me to explain the way forward on this incorrect parcel that I have with me, 2 weeks later, nobody has contacted me - they are quiet. Every time I have to complain on social media , and even on Friday I complained on Twitter and was ignored as usual. I need them to collect their tap and either deliver the correct tap or refund me my money. Please help as I am tired of the lack of service and delivery from Makro thereof. They don't respond to emails, it is difficult to get through to them. They make a lot of empty promises on Twitter when they finally respond.
