Makro and LGM Essentials.

So, this is what happened. I wanted to buy a splitting unit with an hdmi and VGA inputs and an hdmi output. So I went to the Makro app to check if the product was available. I saw that it was and then called Makro customer care to ensure 1, that they did intact have the product in stock and 2, whether I could receive the product within the allocated timeframe. I was assured that yes they did intact have the product and that it would arrive within 2-5 days. I then proceeded to place the order. When the order arrived, I noticed that the seller (LGM Essentials) had sent the wrong package. I had paid for a unit with an HDMI output which retailed at R359 and received a unit with a USB output which retailed at R289. I instantly opened the app to log this issue. I was willing to keep the product they sent if they sent me back the balance or gave me store credit OR they could send the correct item and take the one they had sent back. Unfortunately the only thing you can do on the app if you have issues is to log a return. So I did, and I clearly and explicitly explained what I wanted. I received no communication from Makro until the next Tuesday morning when they contacted me to let me know that the courier would be coming to collect the item and that they are going to give me a refund. I let them know that I would rather they sent the correct item because I needed the product and failing that, they could just give me a partial refund. I received no response. The courier came and I didn't give them the item. And then today, Makro calls me and basically let's me know that I can either give them the product and get a refund or I keep the one they sent and not received anything. Here's why this is a problem for me: 1. I called before I placed the order to ensure that they had the product and they affirmed that they did. 2. The seller sent the wrong item on purpose and did not communicate anything to me. 3. At the time of purchase, the seller knew that they did not have the product I ordered but it was not indicated on the app nor was I told by the consulted I spoke with before placing the order. 4. They are blatantly refusing to pay me back the balance even though the fault was with them. I cannot afford to not have the item and they *****ed me on purpose so they could make an extra buck. This is very bad business practice by Makro and LGM Essentials! My trust rating for this retailer just went from 5/5 to zero.
