Rotten meat, lousy excuses for not refunding

I bought oxtail on special for R99p/kg at SPAR Kilnerpark. I proceeded to freeze it but there was a note previously frozen. Anyhow I put it in my freezer. On Sunday 10 Nov we cooked it and it had an awful smell. So I reach out to the stores Facebook page and messenger. The latter responded it's not a workplace platform. So I can on 15 Nov. The person picking up the call tells me no off late loads of people are returning meat so might be their fridges. Then she gives the phone to the manager. I explain the story and he proceeds to tell me there is a sticker that says allow the pack to get air before cooking and the smell goes away. Firstly that's very alarming because why must there be a smell in the first place? Then he says no I should've returned it. Imagine reaching out, then such a response. How do you walk around with rotten meat? So I dropped the call because it was clearly not going anyway and I threw the meat out. I experienced such with a different store and was offered something else despite having thrown the meat away.
