expired Northlane debit card
I closed an ATT landline account a while ago, and some time later ATT sent me the refund on my unused negative balance in the form of a Northlane.com debit card. But I didn't really pay much attention to it. But when I went to activate it, it didn't work, and then I noticed it expired, valid through 9/2021. Actually, I'd thought expiring debit cards had been illegal for a while, at least in my state (CA). Guess not. What am I supposed to do? Will ATT extend it or issue a new card or send me a check? If that's not their policy, I'd really like to know what happens to this money I'm owed? Does ATT keep it? Or does Northlane keep it? Or something else? Thanks all.
