How would you deal with the situation?
I would go back to the "third party company" and get them to finish the job.
Because of the nature of the interconnected tables in phpBB it would be very dangerous to try to manually change topic and/or post ids unless you fully understand database structures.
You might want to try posting in the Wanted forum to see if anybody is willing to try and sort it out for you.
