FYI, per Cruise Critic rules, we don't name or discuss travel agents.
I agree, your travel agent needs to link the bookings. Not sure you will ever be able to look into a booking at the HAL website that your name is not listed as an occupant in the room. You will not, foe example, be able to book excursions for people in the other cabin, if your name is not listed as occupying that cabin.
