Absurd Service receive from Takealot.

My wife and i purchased 2 x 2in1 scooters for my boys as the one celebrated his 4th birthday today 10th July 2023. Just to give you abit context, we normally purchased 2 item (one for each) as we cannot just purchase only for the one and not for the other. On Thursday the 6th July 2023, we purchased the above mentioned items whereby we made immediate payment and the item was listed as priority, which meant next day ready for collection as per takealot site. Initially we could have purchased the same item for R448 but the system reflect that there was only 1 in stock. We then purchased the same item for a slightly higher price which was R550 as it was marked priority with the next day delivery or ready for collection. We received notification on 07th July 2023 confirming order number *** is ready for collection. I collect the scooters on Sunday the 09th July as I unfortunately couldn't collect before due to unexpected activities. When i collected the gentleman only brought 1 scooter. I immediately noticed the error and enquire about the second scooter as we paid R1100 for 2 scooters. They lady then stated that it might be a split order as system only reflect 1 and i responded with impossible as both scooters was listed under 1 order number and provided the order details whereby the quantity reflects 2 items. After they scanned the QR bar code, the system then changed and reflect the other scooter will be ready for collection on the 11th July which is the next day.... and then the system changed again and stated ready for collection on the 17th July. Bear in mind that this notice was only available after i collected based on confirmation received that both scooters as it was one order number was ready for collection. The manager agreed and tried assisting. He then emailed the relevant departments and individuals such as the operational manager, regional manager and the head office manager, explaining the situation and requesting assistance. He also requested if the missing scooter could be on the next day delivery at 09:00 sharp as I said i want the item by 09:00 latest. The manager explained that the first truck arrives at 10:00 and i then accepted and agreed to collect the item but then i need to be guaranteed that the scooter will be included as i cannot be inconvenienced due to an internal ***** up. Remember Takealot is not covering my fuel cost and i cannot be driving up and down. This morning the depo confirmed they received a response as one of the individuals then rep**** to the email and stated an agent will be assigned to assist. I then did some more follow ups without any success. I then decided to go to the depo to collect my scooter that i have already paid for but without any success. I again stressed the fact that i am not going to disappoint a kid whereby you only purchase for the one and not the other and if i wanted to I could have easily purchased the R448 scooters and accept that it will be ready a day after my sons birthday but instead i paid the extra for priority service with a promise that the order will be ready for collection on the 07th July 2023. I was ****** as i paid for convenience and priority service which i did not received. I had to decide if i should give the scooter to the one and look helpless as the other son will ask where is his scooter.... Todate i have not received a call from Head office to fix this matter and the birthday is basically done. What absurd service received.
