Online - Worst experience ever

So like many other I bought stuff from Makro Online on Black Friday thinking I could just go pick it up after all the rush is over and done with. Well its been 7 days and I could have just thrown the money out the window for all the good it did. They haven't even processed the order yet, not to mention that they also over sold all their items thinking we the customers will just be fine with waiting for their stuff. That's not how you run a business, you cant sell more items that you have. When you sell online you commit to a delivery date, not 21+ days after. That's BS. And don't even think of asking for a refund, Another 14 days for that to happen, if you can even get a refund out of them at all. So now they force us as the customers to wait. 21 ****** days, like i was planning to spend December in JHB for my stuff. There's a place in hell for them
