Woolworths food gone bad

I am writing this complaint and hope you do understand where I come from. Monday I went to Woolworths to buy meat for the house and put everything straight into the freezer, Wednesday I decided to make the sirloin steaks I bought, then after about 2 hours eating the steak me and my partner actually started to get sick, stomach cramps, fever, stomach upset the whole night and still busy. So I bought a whole bag of this steaks and I didn't look at the label for an expiration date because shopping at Woolworths I never felt the reason for that, I always had fresh food without having to get sick and thats the reason why I buy my meat from you or butcher only and not the other retailers. I am very disappointed that the caslewalk branch didn’t make sure that these kind of things, don't happen. I feel also like I have wasted my money in this bag of meat so I need to throw away the whole thing because I don't feel like getting sick again. There was someone that called me on Friday but I was busy and asked she should call me back in 5 minutes, well I am still waiting. I cannot believe this is the new standards of Woolworths .
