Mama's Pies Sausage Rolls are Sour!

We bought a box of Mamma's PIES Sausage Rolls. The BB date on it is 21/07/21 and the pack date was 22/07/20 23:29:00 from Pick n Pay Sherwood, Brakpan on the 28th of March 2021 09:26 - The Slip number is ***

We just baked the pies and the smell that came off them were awful, they are sour and will make one ill! I have a photo of it if you need.

Needless to day, we won't be buying Mama's pies again!
