Month old yogurt sold

I am absolutely disgusted by checkers cape gate. One would think that the quality of products provided are top class however i purchased items on Saturday the 15th October, one item was a tub of yogurt from Fruits of the Forest. Today i opened the yogurt only to discover a bad smell coming from it. The yogurt expired on the 2nd September 2022 a whole month and 16 days later but it was still on the shelves right infront. Tell me how am i supposed to ever feel comfortable again using their store. Absolutely disgusting and to top it all off they dont answer their phones.
