Coles Supermarkets Australia

I went to coles on the 24th of april 2020 to do some grocery shopping around 9pm. I bought a jar of the mentioned spread 1 day ago with a valid date of expiry and I found out that it is moldy when I opened it. The jar says best before 23/6/2021. The day it is produced is 23/3/2020. This is unacceptable. They should be monitoring the products that they are buying.
