Makro doesn't deliver

I ordered seven items online on 5 January (order number MAK587061), one of which was delivered on 6 January - six items missing. On Saturday 6 January I queried the missing items and was told in the response from Boitumelo Moalusi on Monday 8 January that the query had been escalated to the relevant department. I followed up on Thursday 11 January as there had been no further response, but no reply. Saturday night/very early Sunday 14 January morning at just after midnight, I received an email saying the items (all seven) had just ben delivered. I certainly didn't received anything at that time. Makro is sitting on over R500 of my money for this undelivered order. I want my items. All communication has been in writing on email. Importantly can Makro please be more responsive to queries and follow up on escalations promptly. This level of service is poor and completely unacceptable. Please do NOT call - email only Thank you.
