So Metabank says BBB deactivated the cards and BBB says it didn't do that. Try to arrange a conference call between you, Metabank, and BBB. Even if the cards were deactivated by BBB, BBB has to return the funds used to purchase the cards. Where did those funds go?
The BBB lady didn't explicitly state they didn't deactivate them. It was more along the lines of her telling me she "found the transaction" but that my "card number doesn't match" (first 4 and last 4 do, but she claims the middle 8 don't) and that she couldn't/wouldn't talk to me in more detail because of that. I'm thinking going in with the deactivated MGCs, Happy card, the receipt from when I purchased that Happy card, and the card in my name that I used to buy the Happy Card might be my best bet to convince them there was no fraud involved, since I assume that was their rationale, and that it was at most a "misunderstanding" involving the use of Happy cards.
