Poor customer service

I am disappointed with the poor customer service provided by the acting manager on duty at Pick n Pay Westville Junction. I purchased a loaf of bread at the Pick n Pay Pavilion on Wednesday 22 September 2021 with expiry date of the 25/09/2021. I intended to consume the bread on the 24/09/2021 and I noticed that the bread had mould on it. I took the bread back on Saturday to the Pick n Pay Westville Junction as the branch was closer to me. The manager on duty was extremely unhelpful and she told me that the bread had expired, although the date was still the 25th and I need to take the bread back to Pick n Pay Pavilion as I did not have a till slip. I asked her to assist in checking my smart shopper card to confirm my purchase and she refused. I also asked her to contact Pick n Pay Pavilion and she said that I need to go to the store and she refused to assist. I am so happy that I am a loyal customer of Checkers. Checkers will gladly exchange an item with no issues. I am shocked that I was asked to go to the store that I purchased the item. I drove to the Pick n Pay Pavilion and the item was exchanged without any fuss. I only pursued this complaint as a matter of principle. The acting manager on duty was happy to give me her managers number and the number for customer services without trying to resolve the complaint herself.
