Chicken Livers, Boerewors totally off

Hi, my husband and i shop at Food *****s Market a lot. Especially Menlyn and Silver Lakes branches. We bought chicken livers last week Tuesday the 28th August and we cooked it, they were off with Gall Bladders stuck in between. then we bought again thought maybe it was a bad bunch and it was off again. So we have been totally turned off chicken livers. Yesterday we went to a braai and we bought the BLUE BULLS BOEREWORS. We braai'd it and too our embarrassment it smelt like OFF EGGS when it came off the braai. I am sorry but this is totally disgusting that you can think its okay to supply food like this and i am guessing we are definitely not the only people complaining. Im horrified.
