Purchased M&S Digestive Biscuits 75p. After eating a couple realised the biscuit was covered in a mold like substance. It had coated the next biscuit. Hence I didn’t know if the eaten biscuits had the mold on them or not. What would a customers do for instance or what would Chairman Stuart Machin do.?? Yes I returned to store only to speak to a disinterested Manager who was shown the biscuits. She named the substance mold. She seemed amazed that I wanted to know what I may have eaten. Not once did she say she was sorry. She seemed to think refunding me 75p was a bonus. I pursued the problem with customer service but no one seems to be able to tell me what the mold was or how it had happened. I bet Stuart Machin wouldn’t have this problem, but then again would he eat a M&S Digestive Biscuits. Three attempts with customer service have resulted with “ We are so pleased you have been able to obtain a 75p refund. Along with the last CS person emailed Hi Lucy ( I’m not named Lucy). Surely it’s a normal question to want to know what one may of eaten ?. Stuart you need to sort your Management Staff, Customer Service & most of all 75p Digestive Biscuits out.
