Payment for goods that I don't have

I placed an order on the 20 January 2021, it started to appear on the system on the 22 january 2021 that is been sent to the courier. Up until today I am still waiting for the goods but they are busy sending me statements to make a payment. What am I actually paying for because I have been waiting for those goods for a period of a month now. The courier company that was suppose to deliver will come late. When I tell them to deliver in between 8:00 and 16: 00, they just said I am the last on the route to get deliveries. That means I will never get those goods. I have tried to send an email to Homechoice this morning when I wake up. Unfortunately I have been blocked from sending them emails. I wish they could stop sending me invoices and promotional messages. I do not want to hear anything from them as much as they have blocked me and have not yet send the goods but expect money from me.
