I'm sorry for the trouble you're having. One of our team members will reach to you via support ticket and will assist you in adding verifying your credit card. Thank you.
I have been prompted to confirm the card that I have added to my client account. I can't see any recent charges from UpWork on my statement for September. And so, the problem lies in the fact that I only have a few days left to verify my card, but no way to accurately guess the verification numbers.
Your help would be greatly appreciated.
