I agree with the others who said to call the manufacturer and report this. Not only to help yourself, but to let the manufacturer know that this has happened and that their bags are not holding up as they should. You should not have to take on the tiresome task of doing this yourself, as it is the manufacturer responsibility to put their product in bags that do not degrade over time. Or, if they know that this is happening, then they should state this problem on the bag so that customers know to take the batting out of the bag and toss the bag right away. The manufacturer should replace your batting at no cost to you.
