Foods are off

I used to love shopping at Food *****s due to the rather healthier option and value for money, however, this is the 4th time I have purchased goods and they have been off, first was a platter of eats which appeared to be good but on opening found to be mouldy underneath, a wrap I purchased a while ago for my man to take to work was off and then a wrap was purchased 3 weeks ago for myself also off (this I returned and was given my money back), and now we purchased 2 sandwiches on health bread and my man's is off, too scared to try mine, I'm really upset and put off their food, once you can understand but 4 times is ridiculous.
