Help Desk Ticketing

When contacting the MDA Support Center, please be ready to provide your contact information, which will be used to create an MDA Customer Service Help Desk profile. Once the profile is created, MDAs can assign ticket/reference numbers for your inquiries. Ticket numbers can be used to connect you directly with the MDA assigned to your inquiry when calling the MDA Customer Service Help Desk or to help route emails to your assigned MDA.

Provided the MDA has the information needed, help desk tickets will be created within 24 hours. MDAs will attempt to provide a resolution to the customer within 48 hours. If the MDA cannot offer a resolution, they will provide updates of their progress to the customer every 48 hours.
