Uh oh! We're unable to process your payment. Please call your card issuer for further details.

Question

I’m writing to express my frustration regarding the ongoing issue I’ve been facing while trying to schedule the SC-100 Microsoft Certified Cybersecurity Architect Expert exam.

Each time I attempt to complete the booking using my VISA card, I receive the following error message:

“Uh oh! We're unable to process your payment. Please call your card issuer for further details.”

I have already confirmed with my bank that my card fully supports international transactions. I even tried using a different card, yet the exact same issue occurred.

This has been an extremely time-consuming and frustrating experience. I’ve been attempting to schedule this exam for quite some time, and even after contacting the Pearson VUE support team, I was told to wait until the next business day — which completely disrupted my schedule and plans.

I would really appreciate it if you could urgently look into this matter and provide a clear resolution so I can finally proceed with my exam booking without further delays.

Align profile & billing data

• Confirm the country on your Microsoft Learn profile matches the country you’re entering on Pearson VUE’s billing page; then re‑try. Misalignment can break discounts and checkout.

Hi @Huy-K

Thanks for your assistance.

In the past, I successfully completed the payment without any issues. I also asked my friend to register on my behalf using a different browser, network, and card, but the same error still occurred. I also checked the country on your Microsoft Learn profile but there is just only "Manage email preferences", and already matched with the one I entered on Pearson VUE’s billing page.
