If they’re structural walls, they’ll have had to apply for building regs and the local authority should have a record.
If they’re stud partitions, I wouldn’t worry.
One was probably stud, don't know about the other.
The fact that they've just denied removing any walls is the concerning bit.
Surveyor (ironically) might help you?
