DONT BUY PIMANS PRODUCTS

good day, i bought a piemans mighty fine sausage roll from Marcello's supermarket in Sparks road in overport, durban on the 04th April 2020. I placed it in my freezer and decided to bake it in the oven on the 05th of April at 5pm. After eating it i felt very sick and i started to feel nauseas and the vommiting and a runny tummy brgan, after looking at te package i noticed that the sell by date was the 04th April 2020 on the same day that i bought it. i feel like this has been old stock of this store that they were selling. how can this store sell this product on the same day that it is expiring. I am really ****ed off and im going to take legal action and contact the newspapers regarding this. How can RCL Foods allow this store to sell these old products. I have the following info of the product that was on the packaging 05/04/19/MFSR/1/M1 USE BY 04/04/2020 BARCODE *** I WANT RCL TO LOOK INTO THIS MATTER
