Bad customer service on a order

I have placed an order online with Afrihost, on 23rd January 2018, I followed up via telephone on order on 26 January, I was told they are out of stock. I contacted them again on 29 January I was told that the courier cannot get hold of me only to learn that they have old non-existent contact details of mine of which I have updated with my latest numbers when I placed my order. Today I got told to contact the courier company myself but no reference/ tracking number provided, the courier company tried their best to assist me but only to find that there are no delivery for me.

I am fed up with this poor service, if Afrihost don't tell the correct story on the status on my order I would be prefer to cancel this order.
