Online order: Missing staff

On the 27th of November, I purchased a case of Belgravia gin and tonic (24 X 440ml) online. The case was supposed to come with an additional 6 pack of 330ml. I selected to collect the order at DSV Lockery at Engen in Rietondate. I went and collected my order after i recieved my pin. I noticed that the additional 6 pack was missing. So I called Makro online and was advised to go to the nearest Makro. My nearest Makro is Wonderboom. I first went to the liquor store and they didn't understand what I was talking about, then directed me to the online office. First 2 people I spoke to didn't help at all, instead, they gave me attitude. The said the order was dispatched from Riversand in Store in Midrand and I should go there to rectify the order, 59 km away. The next person who assisted me she said she will escalate and call me back. That was 2 days ago and I havent received the call. My take is she just wanted me to get out of her site. I wasted my time and petrol going to the store and never get help. People use onle store to avoid travelling to the store to get such poor service.This is the 3rd time I am experiencing the same issues with Makro online. Last year I purchased a Fridge that came with a Microwave online, when I went to wonderboom store to collect, I was told the microwave is not included. I had to search for the advert to show them what am talking about. The second time I bought a bottle of gin that included 6 pack of Indian tonic online. Went to wonderboom to collect and was told the 6 pack was not part of the special, once again i had to produce the advert to show them what I was talking about. Am not surprised to see lots of complaints and poor rating on makro online, worse service, even the people in store don't care about customers
