Cooked Chicken, rice and veg meal sour and molded

I used to buy from Spar Lyttelton often as there was a variety of cooked options for a quick lunch, and I was willing to drive from my workplace to buy there. I was utterly disguisted when I opened the container today to find the rice, chicken and both veggies (mixed roasted and spinach) was sour and molded. I had to throw it straight into the bin. Gross. The container says it was packed yesterday (25 September 2017) and to be sold today (27 September 2017). Impossible for food to go off so quickly if it was packed yesterday. Myself and all my colleagues will not buy from there again.
