PRODUCTS EXPIRED

I Normally buy from PicK n Pay Farrarmere but on two occassions I have stopped at Brentwood Park Pick n pay and have bought something only realising when Im home unpacking the groceries that something has expired. I thought the first time this happenned about a month ago, people make mistakes so I let it go. Yesterday 20/4/2015 I stopped at Pick n pay on my way home from work and bought the pick n pay low fat yougarts which I give my kids for school on unpacking the groceries these yougarts were expired. The date stamped is sell by the 16th use by the 19th. The first occassion was with a loaf of bread, when opening the bread saw that it had aleady started with mould. It is not only a waste of money but it annoys me that these things are not checked on the shelf daily before someone goes in to purchase groceries. I dont have time to walk around everyday I go to the shops to check the dates on everything before I purchase. when I get home it is 6.30 and when I leave to work in the morning it is 6.30. I dont have the time to run up and down to the shops to complain and take things back. I rather discard them myself. Im very dissappointed.
