Charged me for more items then what i took

Queenswood SUPERSPAR ********** The first time in many years that i reviewed my till slip as i am a weekly shopper @ Queenswood Super Spar i found that i was billed for an extra 2L Pepsi as well as a extra cucumber. The cucumbers were also billed 3 Rand more then the price on the item itself, when i told my son about it he told me about a month back he was charged for 3bags of ice he never took... i am very disappointed a wanted to bring it under immediate attention.
