Stationery ordered online never received. No reply to emails

I placed a stationery order on the 18h Dec online with Waltons, taking the opportunity that those days were delivery free. Payment was made straight away and I received email confirmation that my order was being processed. Details: Bidvest Waltons Confirmation Order #12927. 2017/12/18 11:53:25 Payment Received. I never heard a word back. I followed up with an email to their Help desk, no reply, I called and heard that delivery would happen the 23 or 24 December. No delivery. I left for an overseas trip and left a letter at my office so any colleague could collect. No delivery. Emails were sent and neve rep****. This is beyond any acceptable level of service. Can I have what I paid for?
