Poor service. Spoiled product

Woolworths disappointed me yet again, both in their service and quality of food/products. I bought cheese yesterday and only realised when I got home that it eas spoiled and had mould. I reached out to them on Twitter, and even explained that I live far away from my closest Woolies, and that I would only go back after two weeks I get time off work. They told me to return to the store for a replacement or refund. When I asked them (on two instances) if it would be fine to return the cheese after two weeks, they didn't respond. I even sent them an email but the only thing I got from there was an automated response and nothing thereafter. I am extremely disappointed. If pictures were allowed on this platform, I would ave attached them to this review. They pride themselves in providing quality in both their products and service. But I've experienced the opposite, twice!
