Moldy Phanda Burger meals

I bought 3 Phanda Burger Meals for my kids at Steers Vermeulen, Pretoria Central. Went home in PTA West and one of my kids (6) ate without even looking, the second one (12) stops eating and shows me mold in hers. I open the last one that was meant for my 13 year old and the bun is covered in mold, my 2 kids ate some of the molds. This wasn't even kept over night, they ate as soon as I got back. I bought the burger around 15h10 and by 16h30 the kids were eating.
