I bought Goldi Frozen Chicken and it was off!

I did my groceries at Checkers on Saturday morning around 9:00 am 10-00 am. I bought 4 2kg braai packs from Goldi Frozen Chicken mixed portions. When I cooked the chicken it was off, it was the worst chicken I have ever eaten. And this was on sale it makes me question if it was purposely done to get rid of the rotten braai packs from Goldi Frozen Chickens. After this terrible experience I will NEVER BUY any meat nor do any of my groceries from CHECKERS this is unacceptable. Now my fridge is full of rotten chicken!!! And there is nothing they saying they are getting better and better with instead they are getting worse!! I am really disappointing.
