Incredible Connections refuses to cancel order for goods not available

This is not what I expect from a big company such as incredible connections. I ordered something from their online store on Sunday. On Monday I get multiple phone calls from a branch to say that the item is out of stock, do I want the floor model and will I be fetching it from the store. I live in a different town, I asked if it is damaged and can they ship it. She says no it is not damaged and she will ask for advice and get back to me. She phones back, the product is damaged – what was the point of the first call then? She says I need to provide her with proof of payment. I have no proof of payment, I paid using the online platform. I phoned the call centre. She had no answers, placed me on hold for about 10 minutes and the line dropped. This morning I phoned again, no answers and the line is dropped. I phone again. I ask the person to phone me back if the line is dropped. No answers, the line is dropped and no one phones me back. The social media messenger person keeps telling me that I have to wait 24 – 48 hours for a response. WHY? You say you have no stock, all you need to do now is send me an e-mail to confirm this and to cancel the order. It has been 24 hours since you realised you have no stock, why is Incredible Connections refusing to send e-mail communication or cancel the order? Why does no one know what is happening? Why does your website state that the product is in stock if it is not? I feel like I am being ****med and that you are *****ing from me during the festive season. Way to keep a customer coming back to your store you bunch of *********** *******.
