You are the prawn

I was at pick n pay soneike the pricing by the prawns showed R64. I paid left the store while walking I checked my slip and it showed I paid R99 for the prawns. I then took it back. The lady that assisted me has no form of customer service training and spoke slang to while assisting me that I questioned her client service language and she ignored it and just refunded me without any explanation. I even had to walk her to the fridge to show her. I told her price you see is price you pay and she called John the apparent manager who said he can't give it to me at that price if I walk back to the freezer I will see the pricing well I took a picture of the pricing and looked at the labels from the bottom up each like had a price. I didn't want to argue or make a scene but as usual so I left the store. First of all pick n pay soneike your staff needs to have customer service s****s training and learn not to speak slang, people management s****s and complaints resolution s****s. I want my prawns thanks.
