Late Delivery/Out Of Stock

I place an order on the 21st December 2018 and I still haven't recieved it. I understand that it takes 10 working days and today 04/01/2019 is the 10th working day. I made contact with customer service this morning and the person I spoke to was of no help at all. My husband eventually contact them aswell and he tried asking them if they can then have the Store arrange for us to pick up the delivery at the store instead because we will be going away and no one will be home should they even deliver next week. I told the Agent when I made the 1st call that we needed the items for when we go away as it was for my daughter. He checked and could see the same thing that I did that the order was in "Progress". The Agent That then spoke to my partner tried to assist with having the things packed in store but to my my surprise I then got a call saying that they are "Out Of Stock". Why is it when I placed the Purchase online it said ABSOLUTELY NOTHING OF ITEMS OUT OF STOCK. I'm disgusted by the service that I have received as that items were IMPORTANT. Why is it that MAKRO can easily deduct the money from my account and then tell me that they Out of Stock and then to top it all off they only Notify their Clients 15 Days Later, on the day it should have been delivered. It's actually pathetic if I must say, the items were NEEDED, you guys have no idea how much you have inconvenienced me. I want my Funds to Reflect in my bank account just as fast as you guys have deducted it For Nothing. Please work on the Services you guys Render to people, this is Treating Customers Unfairly.
