Woolworths Patties have bones in it

My family, friends and myself are huge supporters of Woolworths especially the food division. As of late, I have been disappointed with the quality of their food. I recently bought a pack of beef patties and whilst eating it, I found that there were little pieces of bones in it. my husband had 2 burgers and in both there were bones in it, I had one and there were bones in it. We threw the rest of the patties away as we were to afraid to eat it thereafter. Luckily, I didn't give my 3 year old daughter a patty as I usually would. it was very disappointing. I just want Woolworths to be made aware of this.
