I bought a washing machine In store at Makro crown mines and was told it will be delivered on Wednesday washing machine was not delivered and I got a call the following day saying that the sales person gave me the invoice by mistake so I should come back to the store and give them the invoice then they will deliver the machine , mind you what I have is a copy and they even sent it to me on email meaning they should have the invoice too . They said if I don’t come to the store no machine will be delivered ,not a great service from Makro
