I feel like I've been ****** by MRP!

Money has been debitted from my account via your online app with no email or order number being sent to me. I have sent in numerous emails to customer service. When calling your call center I'm literally on hold for 20 minutes. No feedback from you guys. I am disappointed to know that It was an order of the amount of R1800 which I feel is upsetting me because it is a lot of money to be taken just like that with no explanation from your side. When I went back into the app the items which I have paid for is still in my cart and shows that some of the things are out of stock.(bear in mind when adding to my cart at the time this was not the case else I wouldn't be able to check out and money would not have been deducted in the first place) your customer service sucks big time no help whatsoever and I see that this is a common complaint. Can you guys please be more helpful when it comes to a matter like this. I feel like I've been ****** and that MRP is just avoiding me.
