Marinated Chicken

I purchased a marinated chicken on the 29/12/2019 around about 5pm, went home only to find out the chicken was off. Spelling so bad and turning green. This was just taking back without any apology or reason to this. What poor services. How can the store stock shelves with off products. An its a big franchise and this is pathetic quality. I cannot verify the bar code because slip was taken by store.
