Spoiled / Rotten hot food

I am a regular customer and purchase their hot meals often. I am starting to run out of fingers to count all the occasion of buying off / spoiled hot food. Insult to injury is when you get home and want to eat and realize its off and then you are minus dinner for the evening. Not to mention the horrid feeling of explaining to my elderly mother in her 70's that there is no dinner. I am getting very frustrated to throw my money in my dustbin when I get home.
