Disgusted customer

I am a very frequent shopper at Woolworths store's, recently i bought some dog treats and when i got home to give them to my dog's noticed that it was moulded. The expiry date on the package was 07.22. I took it back to the store and reported it to the store manager that was present. Yesterday i went to Woolworths Pavilion to do my grocery shopping and found the same treats on the self and all of them were moulded. This made me very upset and disgusted so i asked for the manager again. Another gentleman was there and i explained to him what i experienced a few days ago but he was not interested in what i was saying, he said that he didn't know about it etc.... then went on to tell me that i was being rude and attacked me for being upset about rotten dog treats on the shelf. This is not the first time i experienced pathetic service from this store and i will also be reporting this to the department of health. Why have a pet isle when no gives a damn about the stock?????
