Zero communication

I placed an online order on 26/04/20, ***. Unfortunately, I had already had an item in my basket from previously and this was added onto my order, which I accepted as my error and paid in full. This was a cosmetics item from Mac. After paying for the order, I searched for another Mac product and it appears that Edgars does not stock Mac online anymore. I went to the 'help and support' page online and sent through a message requesting that the entire order be canceled and I be refunded in full. Due to the other items being skincare products, I assumed they would not be delivered anytime soon and was able to source them at various other stores. I have heard nothing back, no phone call, message or email regarding this. The order was over R2000, and I would like someone to communicate with me with regards to canceling the order and refunding me my money onto my credit card or into my bank account. As I am an emergency nursing sister, I have been working very long shifts since the beginning of March, and I am unable to come into the store to try to rectify this or to discuss it with anyone. Please can somebody attend to this matter urgently. I am disappointed in the total lack of communication from Edgars. During this lockdown, I have had to do a lot of online shopping, and I have not had an issue with any other company.
