SWEETS THAT IS SMELLING HORRIBLE

I BOUGHT A PACKET OF MAYNARDS FRUITY FLAVOURED MINI ENERJELLY BABIES AT A SHOP IN THE WEEK. FOR MY DAUGHTER. WHEN I OPENED THE PACKET I WANTED TO VOMIT FROM THE SMELL THAT CAME OUT OF THE PACKET. THE EXP DATE ON THE PACKET IS 07/04/17. ACCORDING TO ME IT IS NOT THE SHOP THAT SELLS THE SWEETS MISTAKE AS THE PACKET WERE SEALED.
