Poor customer service for online purchases - still waiting Makro woodmead

I ordered a few things from Makro online on 26 November. About 7 days later I received part of my order ( please note, that there is no indication from makro that it is a split order for deliveries). I have phoned the call center on 2 different occasions and there isn't really a reason as to why this is the case. I have spent about an hours worth of airtime doing this, and in the last call, I was advised my order was sent to the woodmead Makro, and given their number to try directly contact them. I called them yesterday, and after getting through to woodmead customer services, they couldn't get hold of the online section and I was given their number ( this is about another 15 minute phone call to get to this point) - I have phoned this number about 5 times and it just rings. This is so ridiculous, there is no indication as to why the order was split, noone has notified me of anything, and I am still waiting with no indication as to if/when anything might be done. This is the 2cnd time in the last 2 months that makro has taken 3 weeks to month to deliver my stuff. Definitely learnt my lesson and will avoid any orders with them. They're a huge chain store, how do they justify these wait periods with no reason. So irritated with them.
