The enrolment wizard looked up a programme's base price without any
branch filter, so with per-branch pricing across 7 branches the
receptionist could be quoted another branch's price.

The registration wizard's printed receipt resolved the branch with
Branch::first(), so every receipt printed the first branch's details
regardless of where the registration actually happened.
