Dissapointed

I am so disappointed with the level of service I have received from Makro...on Saturday I went to the Woodmead branch and wanted to purchase, everytime when it was my turn with the cashier a technical fault was experienced by the cashier. I went to 3 different cashiers and this happened to all 3. I decided to use the online system to purchase. I still don't have my goods, when I called the online call centre I was told that the courier company has 4 pieces of the equipment instead of the whole set (5pieces) how do they collect a set only to find out its a 5 piece set?? I must say I am disappointed at a chain that is this big to make silly mistakes like this, I am unable to go anywhere as I was advised that they can not confirm the delivery day. I am used buying online where the goods get delivered in 2 days.
