False prices, Lie about stock availability and then undermine their customers complaints

I am really upset about what Spar is doing with false advertising, incorrect prices and disgusting service from employees when you query the incorrect pricing. I placed an online order on their mobile application at Kwantu SPAR in Alice, at first a lady called me pursuing me to cancel my and blatantly **** saying that the product was out of stock. Luckily at that time the receiver was nearby the store and I asked them to check if the product is indeed out of stock. I was shocked to hear that there is plenty in store. I then called back and asked the lady why she was dishonest about the availability of the product. She said that she didnt know so I informed her that the receiver was in store and that I will reorder quickly and she agreed. A few minutes later the lady calls me again saying that I ordered the wrong product, I told her that I know exactly what I ordered it clearly written. She then went on to say that the pricing was wrong and they made a mistake so she will cancel my order again. I refused asking her first of all why did she lie at first and say the product was out of stock. I have paid for the product and now she is forcibly doing a refund because they made a mistake on their. She was not apologetic and her tone was very condescending. She addressed was very rude and kept over talking me while I was explaining my complaint. She mentioned the terms and condition on the app after I told her that I read the terms thoroughly and nowhere does talk about forcing refunds because of Spar making an error on their pricing. She the handed the phone to her colleague without notifying me and the second lady I spoke apologized and explained that she can not make the final call and she will escalate the complaint to management and get back to me by the end of today. Nobody has called me yet but my order was cancelled again and forced refund paid into my account. What kind of brand is SPAR? They post false prices, Lie to their customers about stock availability and then undermine them when speaking to them on the phone. Adding insult to injury they have not bothered to provide feedback.
