Incompetence at its best.... The Blind leading the Blind

Yesterday at 19h53 my husband bought Nan 2 and he was assisted by Lucky. He asked for hy****yzed milk and the cashier didn't know which milk it was and ended up chosing one on the counter. At 20h03 I returned the milk with him and Johannes attended to us and asked us to return today on Sunday as the store was already closed and the cashiers were already cashed in.... I quote. I went back to the store and I spoke to Johan who was not even willing to hear me out, he practically dismissed me and said he will contact lucky. He left for a while and came back to tell me about a camera footage and omitted to tell me what Lucky said when asked about Hy****yzed milk. I left him with the milk... He can drink it for all I care. I understand that they do not accept returns for baby products, if they had knowledgeable staff including himself non of this could have happened. They had no clue what I was talking about as well and they sell the stuff. I have been so supportive of the store until yesterday. The R72 that I donated yesterday is the last cent they will ever get from me. There are two Spar stores that offers far much better service and my hard earned money will go there. Yes, I have to drive a km more and I don't mind as long as I do not support hypocritical people like Johan, Johannes and Lucky. Especially Johan who has no clue about customer service or customer experience. He is useless at his role.
