*** now MAKRO

So me and my husband decide it is much saver for our family as well as the people around us to order online. Since Makro has a 3-7 working days delivery since your order is place we decided to place the order on 18th of April ( a Saturday). Calculating that it would arrive on 29th of April ( Tuesday) . Remembered the 2 public holidays and then so our babies milk would last until then. Since we live in a small town that does not stock up on babies milk we thought that this is very convenient. But here we sit on 8th of May. No package of Makro. So called on Thursday , 30th of April, no answer can be given on where the parcel I paid for is nor if delivery will take place. On Monday, 4th of May called in again to ask if there is any progress. Finally the person told me the package has been picked up by Dawnwing Couriers. It will be delivered in the next day or two. So now on Thursday, 7th of May I call again to ask when the package will be delivered. Now we don't know if we are going to eat this month or if our baby will have milk. No one will make the phone call to update to tell you that there is a delay in deliveries but will keep you posted. *** am I to do when this is the service you get? Can't get your money back straight away because there is email to be send from one person to another and so goes We can't go buy other groceries or milk , nappies ect. Because we don't have extra money. Please advice!!!!!!!!! The couriers tracking number does not work
