Disappointing Service Delivery

I have been very disappointed this time around with Takealot. I am a frequent customer as a mother of three it does help me to order online. This time, however, was not the case. I placed an order on the 25th of July and was given a notice period of 14 days. I obviously accepted this as in the past they have delivered one or two days earlier than the date estimated. I received a message expecting my order today (3 Aug). They tried calling me once, it ringed twice and as I picked up it was put down, I tried calling back and the call was unavailable. Very happy, I made sure that I made a plan to be at home the whole day to receive my order only to get a message to say it has been rescheduled for tomorrow (4 Aug). This was due to me not taking delivery!!!!!! I WAS HOME THE WHOLE DAY! Called the call center and they couldn't help me, now I need to make other arrangements to try accommodate this error!!!
