Scheduled delivery rescheduling issue

We haven't had a major issue with Takealot before now. We placed an order last week and delivery to my mother-in-law's house was confirmed via SMS and online for 08 Dec 2019 between 08:00 and 17:00, So, as my mother-in-law is currently in hospital, there's me sitting at her house from 08:00 AM waiting for the package to be delivered. At 14:45 I even called the Takealot call center to find out if the delivery was still happening and they said all was on schedule, just that they can't track the driver. I gave them my number, so that the driver can call me when he's on his way to the house, so that I am ready. All was great! At 16:55 (FIVE MINUTES BEFORE THE END OF THE DELIVERY TIME) the Takealot app shows that the delivery has been rescheduled!! Takealot didn't even phone me or send an SMS or anything to notify me of the change. I find this completely unacceptable. It shows that certain companies have no regard for peoples' time. I phoned Takealot this morning and arranged delivery with the help of a very nice guy named Jody, but the fact is still that they *****ed me around the whole day yesterday. Very disappointment and am looking for some compensation.
