bad management service

I went to checkers on Saturday and there was a toy on the marked down shelf. The lady who assisted the Till Operators advised me that she is waiting for the manager to come and confirm as the barcode scanned a whole different price. Upon the managers arrival she had a very erupt attitude and went to the aisle where the toy was. She came back and I was on a call at the time and just started speaking loudly not minding me being on a call. She advised me that someone must have placed the item on the wrong shelf and it is the correct price the lady who assisted mentioned that same is not my fault. Managers should know how to deal with clients on a daily basis- if that is your tone of speaking well then I would like to know how you became manager in the first place. This happened at Parow Centre (I come from a retail environment and I will always mention it to everyone the business I worked for sends you for induction and you learn from the get go how to speak to clients and "customer is always right"
