Checkers must have the worst kind of service!!!!!

I buy parmalat black cherry or strawberry yoghurt 175g everyday at Checkers in Brookside @R4.99 but in the recent days its been scanning R6.99. i kept quiet the first time but today has got to have been the worst day ever!!! i told the cashier about the price discrepancy and she asked her till packer to go have a look, she took her sweet time while we waited and came back with the wrong price!! i then decided to go look myself and showed the girl(who probably cant read) the price. manager came forward but didnt change the price even though she had the damn barcode in her hands, instead needed to clarify with store manager and waste more of my time!!! how difficult can it honestly be to keep prices on shelves updated, how difficult can it be to rectify a mistake the store clearly made. i paid for my other items and left the yoghurt behind but noone could be bothered to atleast find out why i was leaving, maybe only too glad that i didnt give them a hard time!!! Checkers in Scottsville is exactly the same!!!!! never seen such poor service in my life. im gonna say it again, Checkers staff are probably depressed more than anything, underpaid and overworked!!!
