Never received my order or refund

I placed an order for a nespresso machine on 24 January 2022. The delivery date was stated as between 25-28 January 2022. I have not received it to date. I followed up on 2 February and was informed delivery would take place before 4 February. No delivery date or courier details was shared as is normally done for online orders. I tried the contact numbers listed on their website and their email signatures but could not get through. The landline does not ring and the WhatsApp line has one tick. I later requested a cancellation and full refund in terms of their terms as stated on their website and got confirmation that this will be processed. I have tried to follow up for the past two weeks with no feedback. The order still shows as processing on their website with delivery dates moving out each day by an additional day. There is one email address listed with various people responding but no updates on the cancelation process or when internally they process refunds.
