I am facing same problem from last 3 days and no one has contacted me via ticket.
I got notification to enter my country's ID, which I did. I then received message to wait 1 business day. today is 3rd business day and i haven't received any reply.
One thing more
My debit card is on my name, but the name of upwork account is different. Upwork account name is "EDAANS" which is company name which i started a month ago.
I checked your account and can confirm that your issuing bank declined the transaction. Kindly check this directly with your local bank for more information. In the meantime, you can add an alternative billing method to be able to purchase Connects for your account.
