Unacceptable delivery delays

Order number ***. This order was originally scheduled to be delivered 17 March by 17:00 but due to it being delivered to the incorrect courier they advised it will take a further 2 to 3 days to deliver. I can't understand why it will take so long to deliver because it was to be delivered to a courier in Morningside in Durban but was in error delivered to Westville in Durban. The distance between these 2 places is not more than 30 minutes. The drop of address is in Newlands Durban. From Westville to Newlands is much less than an hour so I am really shocked they will take another 2 to 3 days to deliver. When it was time for payment they wanted their money immediately why couldn't you wait 2 to 3 days before asking me to pay? We now going into a long weekend which means even longer I must wait for my order. If my order cannot be delivered on the 19 March I want a full refund.
