You posted this to the feedback section, but I'm not sure it was meant for this area. Can you give some more details on this? Was this post about a particular ADTRAN product?
There doesn't seem to be anywhere else to request customer support. I completed some Adtran tests on the adtran university page and haven't received the certificates yet.
I completed one on 10/28 and received a cert in my inbox 3 days later, but these are taking a bit longer.
