Very unhappy former customer

On Tuesday 06 November 2018 we app**** online for a laptop and on Friday 09 November 2018 the first installment was taken from my account with the promise that the laptop will be delivered within 7 working days. This did not happen and when I made enquiries about this, I was told that there was no stock. I know these things happen, but I feel that you should have checked whether you had the product in stock before taking my money and made promises. On Monday 10 December 2018, I enquired again about the delivery of the product for which an installment was deducted from my account. This time I was told that the product was on its way to me via courier and I was even given a tracking number. I contacted the courier company, but they informed me that they don’t have this tracking number on their records. I even gave my details, but they had no records. I then contacted your call centre again and a different consultant told me that you never had this product in stock. I immediately decided to cancel and request a refund. After being sent from pillar to post, I was eventually given a case number on the Friday 14 December 2018, but it’s been month and I still did not get my money back. Now I’m officially giving you notice that if I don’t get my money back by Thursday 17 January 2019, I will not just give my attorney instructions to pursue legal action but I will use every recourse to make sure that other people as well as potential customers don’t become victims of this ****.
