Bad service from Baratang Fresh food manager Shoprite

On the 25 October my wife and I went to do shopping at Shoprite Signat Terrace shopping centre and we took Kelloggs 1kg from the shelf at the ticket showed R56.99 and Tissues that showed R19.99 when we got to till points there was a price difference on the both, Kelloggs R67.99 and Tissues R24.99 and we spoke to the manager Baratang (Fresh Food manger) on duty who was very very rude as i explained to her and even went with a packer named Whitney who confirmed the shelf ticket even went with a security guard to confirm and he also saw the incorrect shelf ticket. Baratang was very rude, arrogant and she clearly didn't have any customers service as she informed me that she wont honored the price as per ticket and she took photos of the shelf and she is the manager on duty at its her called and i requested to speak to Branch manager who she arrogantly told me he was off and asked to speak to other manager who name is Christie who immediately apologized and assisted me. Baratang is clearly not a position to be a manager as she dont understand CPA rules and the cashiers was more helpful than her. Baratang needs to go on course for Customer service
