Whether you tried to take it off or not, glue on the bag is a defect, I have had it around the zipper areas and have taken the bag back, it will discolor into a dark yellow color with time, take it back, its not your fault that you tried to take it off and it did not work, make sure you tell them to send it back to chanel as defective and not put it back on the floor. Just because you tried to clean it and it would not come off, by the way, it will not come off, you should not have to keep a defective bag.
