Poor Service

I have ordered item for about less than R1000.00 in September 2022. On the 29th of September 2022 I received an sms advising me of the delivery of my order. I waited, until today 10 November 2022, my order has not been delivered. Home Choice has the audacity to phone me for payment and add interest on the bill for the product that I have not even received. Can someone advise me what to do with such, because I have been telling each of Home Choice staff member that has been trying to reach me about the payment , that I have not received my order. This week alone, I have spoken to close to 8 people from Home Choice, explaining to them that the reason I haven't paid for my order is because it has not been delivered 7 weeks after receiving an sms advising me of the delivery. I am really eaxhausted.
