Stop selling us expired food

I never thought woolworths could sell expired goods, worse the product I bought yesterday expired last month already, it was meant to be sold on the 22nd of July, and roughly 15 days later it's still on the shelves. I'm really disappointed. I always check dates, I don't know how I missed this one. I can't believe I used my money to buy rotten food from Woolies. I'm very disappointed
