I cannot begin to convey my disappointment at M&S. They belittled the discomfort and stress they caused me. One of their food products contained a stone which caused immediate tooth pain. My tooth could be broken and I strongly suspect that it is because it's still uncomfortable (sometimes painful) and because I had perfect dental health before the incident. Now worried about it getting worse when pregnant and needing treatment. (It's a bit of a waiting game now for it to get worse or, hopefully but unlikely, better).
I can understand that sometimes foreign objects are missed but what I cannot understand is how this can be described as an "unpleasant experience" and offered £20 e-voucher. Appalling.
