Poor customer service

I placed on the 1 November and I waited 4 weeks to receive my order. I was the only following up. It was one story after the next and the lady on Instagram does not have customer centricity. When I finally received the order, the one product was missing and to date, I have not received the bottle of tonic. After struggling for days to get their manager's contact number, she does not even answer calls. I haven't opened the products yet and happy to return them as I have not received everything I paid for. They are ignoring my request for a refund.
