McDELIVERY DELIVERING A CANCELLED ORDER

I called McDelivery call centre on ***to place an order, after I was advised the delivery fee is R18 I cancelled the order. I clearly stated that she should leave I'll go down the road myself. This lady still proceeded with the order now I have 2 meals. I paid for the order because I did not want to have problem in future. However, this is pathetic, I mean why would do this. This is totally unacceptable. It's I am forced to buy. Order number: *** McDelivery McDonald's Jean Avenue
