Spoiled goods sold

We have been inconvenienced in the most disgusting way. We bought 5kg white star on the 2nd of December at Game carnival mall. It had maggots inside and some had dried up, we took it back.... Mind you we live in springs. So we took it back. The ladies at customer service desk did not even bother to check if what we were saying was true they decided to credit the money to my husband's account, when we arrived at the shelf we could not find 5kg so we took two 2.5kg and it was more expensive than the 5kg.We took it anyway and left. Fast forward to Sunday. I decide to open one of the bags and we found webbs and more maggots... In the sealed packets. Now we have to travel again and take it back to the store. Not fair at all. You can't sell such to people.... We have children. Imagine if I had cooked that *** for my family. I demand a response from Game carnival mall.... This is nonsense.
