Hi Priscilla,
I'm not sure if Heartland ever shipped Broyhill furniture, but I think it's more likely that the prior owner didn't like the factory-supplied furniture and picked up the Broyhill furniture in a local store.
Regardless, the problem now is finding someone who can fix it, or buying new furniture. If you have a local handyman, perhaps he can figure out what's wrong and make an economical repair.
Another choice would be to take measurements and shop for new furniture.
