Bad product received and no communication on the issue I submitted

I placed an order on 27 February 2022 and received the items I ordered. However the bag of oranges I received was of poor quality and is not fit for consumption. I submitted an issue on their app and all I received were automated responses telling me that Checkers would get back to me, up until today I have not had anyone trying to get in touch with me to resolve my issue. I want a refund for it and I will be looking elsewhere to buy my fruit and vegetables going forward. The app also does not give any option for you to get a refund on a product.
