Selling stale goods and changing the BB date

I bought a pack of 4 chocolate glazed donuts yesterday. They were marked full price and the best before date was the same as the rest. I thought it was strange that there was only one pack of chocolate and it was the only one covered in cling wrap. Needless to say, I should have listened to my gut cos the donuts were all hard and stale. Are you guys now simply just changing the dates on fresh groceries so you can make a profit by selling old stock as fresh. Please get in touch or I will take this a step further.

I have sent a message on FB two days ago and I got a generic response asking for details. I have provided them with the details and 24 hours later no response.
