I am currently at boxer superstores Nonesi mall Queenstown at the moment, I’m here to buy 2l coke on the fridge it’s marked R24.99 and the cashier Lwandiso called for authority as it now scans R26.99 and the lady who authorises (Nosi) tells me she won’t give me the coke as it scans R26.99 , I need to pay that amount of leave without the coke if I can not pay in the R2 and that this is not pnp where they can change prices and she voided the sale and left me standing here on the line to go find the person who packs coke to add to the R2
