TERRIBLE SERVICE AND LACK OF COMMUNICATION!!!!!

On 7 December 2020 I ordered 2 items and paid for it. At the time both items showed on the website as "in stock". Due to the fact that I am going on leave on 22 December 2020 I specifically selected items which was not preorder as this can take quite long. I have emailed them and received a blank email back. Since 15 December 2020 I have been sending whatsapp's only to learn that the one item is out of stock? When I ordered is was in stock? Till date they can not confirm when my order will be dispatched. They simply ignore my messages. I will never ever order from them again. It was such a bad experience and I am disgusted. I did send an alternative address but I am not sure if I will ever receive my order. They must really up their game because if this is the way they do business I can not understand that it is still operating. I am not even sure I will receive my refund (have not yet asked) Please just advise me what is going on - Penny Christine Steyn
