Extremely poor service

Firstly I would like to say that up until now I have been satisfied with your service. I have purchased a lot form you guys and to have this experience is unnerving to say the least. I placed an order one 28 Sep 2020 (Order #***1). I was informed at 09:00 this morning (09/10/2020) that one of the items (Kennedy Medium Duty Precision Craft Knife) has been cancelled. The order was then shipped. I called *** and spoke to Anette. She was rude, unhelpful and ended the call abruptly.

It is not fair to the consumer that you guys cancel and item and ship the rest without giving the consumer the option to cancel the order or replace the item, which in this case is what wish to do. I wish to add the "Kendo - Knifes and Blades Cutting Set - Vinyl, Crafting, Hobby (17 Piece)" to my order. The cost of this item is R199. Again, it is not fair that I have to place a new order for 1 item and pay a delivery cost. Please have a look at my buying history and you will see that I have always purchased above the required amount for the free deliver service. This item is in stock with your supplier. If it is not added to the rest of the items I have purchased I WILL NOT MAKE PAYMENT when the driver arrives by Tue, 13 Oct 2020 and I will not be held liable for any costs which may arise.

I am just curious, lets say I placed an order for R550 and one of the items had to be cancelled and that the total cost was now R400. would free deliver still apply? Or would you guys contact the consumer and give them an option to replace the item in order to get free delivery? Or just cancel the order cause you would not make a profit?
