Payment declined, funds there, verified identity with phone support and told it would resolve in a few minutes. How long really?

So I activated the Venmo debit card and tied it to Google Wallet. For the first few days everything went fine, then it declined a $14 charge at the grocery store yesterday. I had the same issue today, even though there are far more than enough funds in the account. I called the debit support, verified my identity with my account number, and then uploaded my ID and a selfie of me holding my ID through their system. The guy on the phone told me it would take "3 to 5 minutes" to resolve. I waited far more than that and it still is getting declined. And their phone support is now closed for the day. How long does it actually take to resolve based on this situation?

EDIT: credit where credit is due, it did finally end up working. Definitely a lot longer than they said, but it did indeed go through fine in the end.
