Supposed to be guaranteed delivery but did not happen

I placed an order which stated guaranteed delivery for Sunday, 4 September 2022 before 17:00pm. The driver then arrives here around 13:20pm and is busy searching his car for the parcel. After checking in the boot, under seats, etc. He finds that my parcel was not packed and states that it is probably still on the truck (does the guys not check that all the parcels they are supposed to deliver are in their vehicle before leaving the warehouse) I then ask if it will still be delivered today and he says yes. I then receive a sms stating that "we tried to deliver your parcel but was unable to" another notification states that" Recipient wasn't available to take delivery, so we"ll reschedule" This is obviously TakeAlot not wanting to take ownership for the F%.# up they caused with a guaranteed delivery that was supposed to have happened. We then try and call the driver but he does not answer, the call center is called and the first call dropped, the second call is answered by Kauthur who advises that she will try and find out what is happening, she then sends an email response within 30mins, she tried going the extra mile by finding out what is happening, but for the delivery guys, I would rate zero stars if I could. Takealot should have a process in place to make sure that the drivers check that all parcels are packed in the vehicles before going out for deliveries, because the way this driver was searching, it seems that others pack the vehicles and they should just trust that all the parcels are there. Not only was the parcel not delivered, we ended up wasting the whole afternoon as the driver told us it will be delivered, so we had to make sure that someone was home until 17:00 to accept the delivery, which did not happen, so today we must end up making sure someone is home again.
