Once you order and checkers has your money there is no way of following up

Once you order and checkers has your money there is no way of following up. They substituted an item from the bakery for rye bread today! No one in my house even eats rye bread. I tried to log the complaint on the app and it takes you through all the steps until you need to submit te query - then it hangs. Dont waste my time. If you dont intend responding to my query dont pretend that you do. You already took my money. Nect time I will stick with woolies where customer care is not just a word!
