Why do you expect them to cover a mistake made by the exhaust installation shop (or whoever installed it)? The most likely root cause of the failure was improper retorquing of those bolts. Most shops just remove those brackets, rather than fiddle with the rubber mounts, which are difficult to dislodge up there.
Another failure cause (not applicable to you) is to use the subframe as a lever to remove springs, rather than using proper spring compressors. Good luck man.
