I went in to buy cat...

I went in to buy catmor cat food, priced where it was packed at R162,99, however when I went to the teller, it read R175,99, so I informed them that 3 label pricetags reading R162,99 was displayed on the shelf, they did find the tags but instead of acknowledging their error, they just said maybe it not the chicken flavour, said they can't do anything about it, they removed the tags, and the manager did say another customer came with the same problem, anyway I can't trust this institute as it's greed and dishonesty is apparent in their manner and attitude towards their customers
