Makro Cape Gate (Pathetic to say the least).

I bought items online at makro and opted for collection at Cape Gate as only that store had stock. The order said ready for collection I even called the store to confirm and they said my order is ready. Sat 29 July I drove from Ottery to Cape Gate with my kids in the rain. I get to the store and they cannot find my order. They call the manager ALTHEA and she says the order was canceled AFTER picking and they are processing a refund. I then go on to explain the situation to her and she can't even look me in the face. The other staff then say the system shows the order was collected. The manager then insists it was canceled and head office instructed them to cancel the orders. I then asked her who is higher than her that I can speak to because clearly she's not much help. She then tells me nobody as she is the manager. She then tells me about sweets orders people placed and they canceled everyone's orders. Now my issue here is this...I saw a product...I bought the product... I paid for it on the 11th of July already. My order said ready for collection...yet the store refused to honor my order after driving 26km in the rain with my kids. My husband then called the call centre and they say the order was collected. So Makro Cape Gate ...where is my order????? I bought 17 packets of lollipops at the advertised price and I want my order. I see Makro has a history of just canceling orders. Do better Makro. You are going against consumer rights and I have no issue taking this further. I await your prompt response from someone higher than ALTHEA please.
