Makro Cornubia pathetic service regarding XIOMI MI STICK

Around June of 2023 I visited the Makro store with my fiancé to return a Xiomi mi stick as it was only going off and on also the screen was going black. We spoke to the store manager at the time his name was Danvir who advised us he knows that there is defect with the stick and he will do an immediate refund. We then advised him that we have two more sticks which we purchased and that we should bring it in and he will do an immediate refund for us. So we did not have time to go immediately as we were out of town. Myself and my partner visited Makro cornubia on the 5/08/2023 and had the worst experience ever. We were told that they need to send it for testing even tho they were fully aware of the defect with the Xiomi mi stick and also they said what the previous manager told you guys we cannot honor what he said. We was at the store for more than 1 hour and 30 minutes going back and forth with the new manager at the time who said he will get the Xiomi representative to test the boxers. So I explained to him that one does not work and it says no signal and the other TV box comes on however it does take time for the screen to go blank and you have to unplug it and plug it on again. So he said he could only return one and the other one we need to take it back home. This has been the worst experience ever especially been a long standing customer with Makro. I would like a refund for the other stick and promised by the previous store manager Danvir and this matter closed. We did explain to them that we was going to buy the Xiomi TV box with the credit amount as that is much more reliable than the Xiomi stick which we did purchase two on the 2023/08/07. We were also told that we cannot redeem our credit to any other store besides the store that we received the credit from however after speaking to head office they told us that we can transfer our credit to any makro store. So at that time they were no stock of the Xiomi TV box in Cornubia so we was without TV for many months. This is *********** service from your staff and they need to go back to training.
