trade in program

Credits should have started in November, December the absolute latest. Have you confirmed that your phone was shipped to hyla Mobile in Tennessee and track the shipment? Do you have proof of shipment or proof of trade in at a corporate store?

Did you meet all the requirements of the promotion which would include a qualified unlimited data plan, purchasing and trading in a qualified phone?

yes kept proof of shipping and acceptance  of the shipment and the plan is still good

Awesome. 

File a Better Business Bureau complaint online. The complaint is forwarded back to AT&T upper management and someone will call you. They will probably give you an email to send your proof of shipment.

You had to be on an unlimited data plan with a minimum cost for one line of $75. The starter plan qualified. The value plus plan does not. Metered plans do not.

Changing your plan well after the fact of your trade-in would not earn you any credits. You would have gotten book value for your phone. If you got $90, then that's what it was worth

As I said; READ AGAIN, I did this on a store because they said I QUALIFIED. Their program is a scam

Everyone qualifies, if they do as the deal requires.  You clearly state you did not switch to a qualified plan till well after the trade in
