Electric Company Does Not Recognize Card

This could be something fluky at DTE (Detroit Electric Company) today but they did not want to add the Curve card as a payment method. The local gas company was fine with it. I just post this here in case the way some places authenticate does not work with the pass through to the underlying card.

TopCashBack’s gift card mall says the charge was declined as well. The underlying card shows it as pending so I’m not sure where the process breaks down.
