Makro Silverlakes terrible service

I made an online purchase (29 July 2022) and it was directed to this store. After a week (05 August 2022) it was still "Order in progress". When I phoned the customer care line for the 2nd time I was told that the store don't have any stock on hand (18 items order). It took them a week to notice they don't have any stock and now I have to wait an extra 7 days for the money to be refunded to my bank account. I ordered things I need in the house (food) and know I have to make a plan to get money to buy this items else where while I wait for the money to be refunded. Previous I also had a problem with this store. Order was placed 07 July 2022 and was packed 09 July 2022. When I phoned 13 July to find out what is the hold up for the courier not to collect it and then the courier was only contacted and items was delivered 14 July 2022. If I didn't phone to see why it's not being couriered it would've also taken longer for courier to collect.
