Unrealiable Suppliers

Makro has normalized cancelling items on online orders because "their suppliers are having difficulties or delays" such incompetency from a big company is disappointing. This has become a norm and its so frustrating ordering and knowing that you might not get what you ordered. If items are sold out why is the product still on the website for weeks showing available? why is there no communication before cancellation. There is also a pattern I have noticed where they'll email "refund" then the same product from the same supplier becomes available at a higher price. These South African brands are really pushing us to use international brands such as Amazon and Shein because of their poor customer service and dishonesty!
