Disgusted with Douglasdale Woolworths

I went to went to douglasdale Woolworths after a super sh***ty day for a peace of cake, I bought my favourite dessert which is the 5 Lamington salted caramel snow rolls . Only to come home and find tiny bugs in it. Its dessert for crying out load why are they not checking their stock before it goes out to the customer. I am so upset as this is my favourite dessert which I'm sure it is for many other customers. Now everytime I buy anything - if I even ho back after this -I will have to check it so I dont go home with bugs in my packaged dessert. I FOR ONE AM DISGUSTED we go to Woolworths because of the value and the freashness as well as the quality. This is unacceptable and when I spoke to the manager he dismissed me by says sorry heres another . MAJOR EWWWWW if I could rate in the - stars on this place I would
