Bad service

What a bad service I got from the store manager with the name at Checkers liquor mall at carnival.The problem was the price of Hunters dry NRB, I took it from next to the flying fish and the price was R17:99 but on the till price changed to R19:99 and I told the lady that the price they it's R17:99 she came with me to the fridge and she said talk to my manager,then manager came and refused to give me with the price I saw said no,then I asked her were the price for this Hunters dry she's said the price it's missed it's not there,then I asked her can the price missed, I didn't get the answer her finally was she's not gone give me the Hunter's dry with the price I saw and she ended up saying she's leaving me to help other customers and I ask her if you say that what I am here at Checkers then she said or choice of words..I said yah neh..we ended up arguing in front of the customers that's the treatment I got there and indeed her word was finally.She even said bodly she's waiting for any complain about this..As if she knows nothing will happen about what she did to me it's like it's normal.Very disappointed with the treatment from the store manager Mantomane,she was not even wear her name badge she writes her name down for me.
