MAKRO BAD ONLINE DELIVERY ISSUE

I placed an order on Sunday 29th June. Delivery date for bulk of the items was 30th June. Nothing arrived. I called several times on the 30th June and could not get any real assistance as to where the order was! I was told then by a consultant that she would call me back - still waiting and still no order. Today I tried to call to cancel my order and did not have the order no on hand. The consultant was adamant he could not help with my mobile number like the others had and refused to put me through to a supervisor/manager - typical, until he had the order number. I was stressed about the whole situation and this made it worse. I then tried again late afternoon and the lady said she was trying to reach the couriers and would call me back as she could not get hold of the store. I still want to cancel the order and have had no success in getting any call backs or assistance. If Makro want people to order on line they definitely will have to up their game.
