Complaint- Delivery delays, no communication

Good Day

I bought a laptop at Makro online, this was scheduled to be delivered on Monday the 1st of Dec, I received a tracking number and everything, at 17:00 in the afternoon on Monday I Tried tracking my order and it was not delivered, Makro had raised a collection exception, saying there was a delay at store to hand over the delivery to the driver. On Tuesday I contacted Makro customer care and was told someone will call me back, that afternoon I emailed them since no one called. On Wednesday I received a call from Makro assuring me that there were a few delays at store, they apologies and promised that I should receive my delivery on Wednesday afternoon as it has been rescheduled for delivery, I :waited again the entire day for nothing, I tracked the order again at 17:30 only to find that Makro raised another collection exception saying there was delay at store and driver could not collect.. I emailed them again to no response, All this time Makro has done nothing to contact the store and find out what is causing these delays, I have to constantly call them, I have lost faith in their service or the lack thereof.. Can someone at Makro give me a definitive answer on when my laptop will be delivered?
