Dulux customer service

I bought paint from makro in Port Elizabeth on the 13th March 2018, but couple of days before that I bought the same paint from builders wharehouse. The color builders tinted was correct and and I was happy. Makro was closer to my house so I went to buy more paint as we ran short, Dulux makro tinted the wrong color. I immediately contacted makro they sent a rep out to my property to investigate they saw the incorrect shades. Dulux rep named Gwen is so called seeing to my query. It’s 2 weeks later no new paint was delivered to my property and absolutely nothing has been done about my problem. I will never be buying Dulux again as there after service is pathetic! No one gets back to me I must keep calling to ask how far are they. My painters have been on site everyday hoping to get paint delivered.
