Makro Vaal Vereeniging Overcharging for item on special

Overcharged for items on special at Makro Vaal Vanderbijlpark On Thursday 24 Novemeber 2022 I purchased16 Boxes of Ellis Brown Coffee Creamer without realizing it's different weights 7 X boxes of 1 KG and 9 X boxes of 750g which the special was on the 750g 2 X boxes for R85 , cashier only counted the amount of boxes in my trolley did not take out each box and put on counter if this was done the problem would have been seen at the time which could then have been sorted immediately due to this which none of us realized the boxes are different weights obviously which will have a price difference so 7 boxes was 1kg and 9 boxes 750g not realizing that some boxes are 1 kg boxes I just took them from the shelf and put into my trolley . I got charged for 16 boxes of 1kg at R61.45 each so which results to an overcharge which I made payment for on my bank card , I have all slips proof of payments The amount that has been overcharged is quite a huge amount hence the reason I feel that if the cashier had taken out all of the boxes to scan this problem would have been avoided and could have been sorted at the time.
