I've talked to both my previous bank and Google multiple times and the bank can't help me and googles support team refuse to acknowledge any problems. It's been over a month at this point and my funds have not been accepted or denied and no one has any answers with what the hell is happening. No emails, no nothing. Just a email from a month ago my money was refunded to a card that no longer exists.
It's beyond unacceptable that I have to deal with so much of a headache too get any answers.
I'm in the exact same position: a majority of my reimbursements have been "succefully" issued to a closed bank account, with no possibility for me to recover the money from my old bank (they ask me to open a new account!) So I've requested them to reject all the reimbursements, in hope that Google could now use my current payment method instead.
