Takealot.com changed my delivery date without communicating

I made a purchase of a washing machine on Wednesday and before I made my payment it showed that the machine will be delivered on Friday.

Yesterday night I checked, the machine was still not shipped. Today when I tracked I see it shows shipped, after 08:00, few minutes later I receive the message that says my order will be delivered on Monday.

It is so unfair because I made arrangements to have someone with me when the machine gets delivered, I am not available over the weekend or weekday as I have work, I made a sacrifice to be available today but Takealot.com decides for me as a customer which day is effective for them to deliver the machine.

Cancelling will mean I will get my money after thousands of years and I can't get it same day to go to the store to buy.

I AM EVEN UNABLE TO CALL THEM, AND HAVE THE OPTION OF SPEAKING TO A BOT, I WANT SOMEONE TO CALL AND MY MACHINE DELIVERED TODAY OR RETURN ACTIONED SAME DAY.
