I bought a stale stir fry

I am highly disappointed in Pick n Pay Supermarket in Hatfield standard plaza,i bought the mc cain french stir fry, which was labelled 14.99 however to my surprise when i got home when checking the slip...it was tilled for 16.99, main problem again is that the stir fry is stale and smells horrible which ruined my entire dinner! On the product it shows best before March 2024🤢🤮
