Pick n pay Pavillion gone to the worms

Received roches as one of the items for my retirement. It was purchased at pick n pay pavillion Upon consuminga few, my son found a worm in it. I cutt open a few and found others crawling with worms and were mouldy. I have it on video. When I took it to the pavillion branch the manager, Portia was unhelpful, rude and arrogant, maybe she saw us as pensioners. She said she cant do anytjong and we must leave. We explained to her that a gift doesn't come with cash sales slip but she was not able to understand us. What a pathetic service from the manager of pick n pay. Disgusted that pensioners r treated with so much disrespect.
