Bought cardigan half price in the M&S sale. Purchased online. They delivered the wrong colour. No longer available in the colour I wanted. M&S sent me email requesting feedback for my purchase. Obviously I wasn't happy and scored 1 star (would have been no stars if I could). Received email today advising they cannot publish my review as the 'moderator' did not feel they could publish my review in which I mentioned 'poor' service. Am I unreasonable to think that they should have published my opinion and only publish the 'good' reviews?
