Online order bad service

I placed an order, ***, on 3 May 2020, they said 3 weeks, I didn’t receive any updates, after week 3 they sent an email stating 3-5 days. I called customer service, couldn’t assist me, been calling everyday, no feedback, contacted Middelburg Mall edgars. They already billed me on the order and I also paid my 1st installment on this order and still I didn’t receive anything. Last week they said its with the courier company, today they said that the clothing that I ordered is out of stock. It feels like I paid someone else to wear my clothes or where did it go. I’ve ordered online a lot of times and receive my package within 3 days. Whenever an item is out of stock the purchase doesn’t go through and you have to select something else.so please edgars, tell me how did my payment go through, after paying the installment and purchase going through without me receiving anything, can you tell me there is no stock. You confirmed the order. Is there something that the customers need to know and when will we receive what we have paid for .....
