I have a feeling that we are missing a few details from OP, but it seems like OP thought his Bluebird account had gone through the Lazarus Pit when he reached out to Amex to get a replacement card, but that was in fact not the case and his ability to add funds to the account was still gone. Walgreens did in fact transfer the money, but there was nothing at the other end capable of receiving it. Walgreens did their part and have now washed their hands in accordance to their terms for these transactions. Amex now looks at OP's Bluebird account and sees that nothing came in and in fact it's not possible to load money into that account so case closed as far as they are concerned. OP's money is in Bluebird limbo at this point. Outside of just "keep trying your case with Amex," OP would perhaps be better served by looking at the
Bluebird thread under MS and perhaps even sharing his case there as he'll probably get better feedback from people that have specific experience with Bluebird.
