For anyone who stumbles upon this later...
You can go to DDOT HQ for a voucher weekdays 9-3PM (excluding holidays). You do not need to schedule an appointment in advance. I wanted to share since we spent over a month trying to reach anyone at DDOT or associated with the car seat program trying to figure out how to set up an appointment, when it turns out they accept walk ins. So hopefully I can spare others the headache.
