Atrocious and suspicious handling of online order

Where do I begin? Literally the worst shopping experience I have ever had in my entire life. I made 3 orders online, it is over 7 working days later and although Makro have marked my orders as complete and delivered on their website this is false. I cancelled the first order because they took too long to deliver and I had to purchase the item elsewhere - I am waiting for confirmation of cancellation and a refund and am expecting an uphill battle here. They have not made the second delivery at all and the third delivery, only a portion of the ordered items where delivered without any explanation. I have called the call center numerous times and keeping getting informed that my matter will be escalated without any resolution. I am beginning to suspect that staff may be *****ing items from the order list - how else do you explain this level of incompetence??? I will never order from Makro again, I would never recommend anyone who wants a piece of mind to order from that store.
