I definitely wouldn't bother the manufacturer with this issue.
I agree with all the people who have noted that this type of batt needs close quilting and that tying will not hold it together - it's got a lot of room between ties to just about disintegrate, even under normal conditions.
But 250 launderings! Good grief! I can't imagine any batt looking good with that many washings. Hope you're able to fix it back up.
