Woolworths bad customer services

I bought some raspberries on the afternoon of the 31st December for a dessert that i was making for a news years social, at around 17:00 I opened the punnet and found mould on more than half the punnet, I was very disappointed and had to make something else. I took the punnet to Woolworths at Bedford Centre only to be told by the manager that he was going to “do me a favor’ as the refund policy was that this should be returned before the expiry date being the 1st January. This after I was inconvenienced, I bought the raspberries on the 31st December and could not go to the store at 17:00 on the next day being New Year’s Day, the manager then called me rude because I said that instead of reciting the return policy conditions, should he not apologize as the circumstances here was that Woolworths sold me rotten fruit, is there not a policy condition that rotten food should not be sold to customers? The Manager was extremely rude .
