burgers bought had some foreign object in it

Hi<br> <br> Bought hamburgers from Woolworths and Friday made three to my surprise there was a foreign object in them and it felt like a enamel piece was not mine that I guarantee. Woolworths is suppose to take pride in the goods they sell and that is why it costs a lot to buy there. Woolworths need to get their service up and running and take pride in what they do.
