Online website faulty and ********** transaction went off. And still no resolution from customer service a month ago

Truly disgusted at the online shopping experience through this company, and the subsequent service I received. I have posted my complaint on the facebook group, emailed them, yet still the issue is not resolved and I'm truly exasperated. On 23/08/19 I attempted to purchase 3 items on this company's website, forevernew.co.za. The total was R2319, which was duly deducted from my credit card. However, no order was generated and the items I attempted to buy remained in my cart. I communicated with the merchant wherein they deny having received any such payment from me, despite it clearly reflecting on my credit card statement. I had sent them a screenshot of my credit card statement, they contacted the financial department who merely said "No funds reflecting." And so they deemed it case closed, and never followed up with me thereafter. I informed them I would report this to FNB as *****. FNB has taken weeks now to get back to me, their credit card division have confirmed that this transaction was definitely deducted from account in an email I received today. I forwarded a screenshot of this to forever new today. I have sent FNB all the copies of my communications with the merchant but, as they told me telephonically, unfortunately they cannot resolve things with the merchant directly; I am the one who has to email and attempt to resolve this with! I cannot get hold of forever new on their telephone line, it forever rings and rings even during working hours! It's really sad because between January and August this year I used to purchase at least 3-5 items from Forever New stores on average. Now I honestly am just disgusted and don't even want to give them any further business or another chance to take my money and deny having deducted it. People have seen my post on forever new's facebook page and have asked me about what happened - and all I can tell them is sweet nothing and that I'm still sitting with my credit card in arrears! My last email was last month from forever new and they never bothered to do any follow up or check that I had resolved my issue or received a refund. Truly disgusted.
