Silver Spoon Company, British Sugar - something in the sugar you have supplied

hi i bought a large bag of sugar as i always do for cakes im a cake maker and i used the sugar for baking several cakes which have gone to customers and the last of the bag i put in my sugar canister, i went to make a cup of tea and noticed floating bits of the top which smelt very sweet and the smell of coconut , i asked a few people to look at it and they said the same, the problem i now have is that i have a nut allergy and hopefully not any of my customers , and i want to put accross to you that could you check your sugar please as there may be more, im sorry to tell you but if i get any comeback i will come straight to you as i have still got some left x i will not leave this here and its not because of the sugar or what ever is in the sugar its my customers im worried about and potentially more so please can you sort this x many thanks
