Makro Online Order VERY SLOW - Poor communication

I ordered a Bestway swimming pool online from Makro - with a 3-5 days delivery timeframe. It is now 10 days later and no delivery. It is apparently being delayed because a 2nd item is not in stock. Makro should still send the main item first, then the 2nd item when it is in stock - just as Take A Lot and other etailers do. My kids are on holiday and the pool was promised. If I don't receive it in one day before I go away on business, my kids have to be without a pool for December. Fail for Makro Online. Their Communication also very slow.
