Promotional Trade-In Credit Never Applied to Account?

I'm the the same boat. I feel scammed. My original rep told me I'd get $200 trade in credit yet so far I only see $21 and no promotions listed in my account.

And I just got off with customer service who "gave me his word" that after two billing cycles I would get my promotional credit. There is no documents showing my promotional credit on my account or given to me by my original rep. No confirmation code. Each person I've seen in person gives me a different story of what might have happened and shrugs.

I believe after what I'm reading online, this trade in thing is a scam to lock customers into a new plan giving them the runaround when we try to reach out. Someone is eventually going to put in a class action lawsuit. 

If I were you, tell them you will put in a bad BBB rating and review. I feel that's the only way they will resolve this. 
 

UPDATE: I talked to someone that finally sounded more knowledgeable and they offered me $80 goodwill credit and apologized my rep made a mistake in offering a promo that didn't exist. It still sucks I'm out $100 from originally promised, but at this point I can't get my trade-in device back and it's a pain to do buyers remorse. Last time I'll ever do a trade-in with them…it's too risky and reps are all saying different things.
