+## Support FAQ 
+
+**Q. Why did I get charged $10 when I added my credit card? When will I get this back?**
+
+A. This amount is not charged and the hold should clear within a few business days. If you have more questions about the status of the clear, you can contact your bank for more information. 
+
+**Q. My card was declined after adding to my account. What’s up?**
+
+A. Please ensure the card supports 3D-secure authentication and is properly configured for recurring online payments. We do not yet support credit cards issued in India as we’re working on adding system compliance with the latest RBI directives. Until we add support for Indian credit cards, you can:
+* Link an organization account to an AWS account in order to access pay-as-you-go features (Endpoints, Spaces, AutoTrain): [Hugging Face Platform on the AWS Marketplace: Pay with your AWS Account](https://huggingface.co/blog/aws-marketplace)
+* Use a credit card issued in another country
+
+**Q. When am I going to get my invoice for pay as you go services?**
+
+A. We bill in arrears and issue invoices for the prior month’s usage - typically the first of the month. So if you incurred billing usage in January, you’ll see the final payment process and invoiced February 1st.
+
+**Q. Why did you charge me multiple times during the month?**
+
+A. If you’re a new HF account using our premium pay as you go services, we’ll process a few billing threshold payments. Don’t worry, you’ll get an invoice for the total usage incurred for the month at the end of the billing period that will include these processed thresholds payments. For more information see https://huggingface.co/docs/hub/billing#billing-thresholds--invoicing.
+
+**Q. I need copies of my past invoices, where can I find these?**
+
+A. You can access up to the previous 3 months from the current month in your billing settings: https://huggingface.co/settings/billing. Click on the “End-of-period Invoice” link under that month’s “Payments & Invoices” and you’ll be able to download the invoice and the receipt. As an example:, if it’s currently January, you’ll be able to access the previous months’ invoices: December, November, and October. You can also check your email as we’ll send a copy of the invoice / receipt to the email address on the account. 
+
+**Q. I need to update my credit card in my account. What to do?**
+
+A. Head to https://huggingface.co/settings/billing/payment and update your payment method at anytime. 
+
+**Q. Oh no! My payment failed, what do I do to avoid a service interruption?**
+
+A. You can pay your bill with another payment method by clicking on the “pay online” link in the unpaid invoice. Click on the “End-of-period Invoice” link under that month’s “Payments & Invoices” and you’ll be able to pay online. You can also update your credit card at https://huggingface.co/settings/billing/payment.
+
+**Subscriptions**
+
+**Q. I need to pause my PRO subscription for a bit, where can I do this?**
+
+A. You can cancel your subscription at anytime here: https://huggingface.co/settings/billing/subscription. 
+Drop us a line at [email protected] with your feedback.
+
+**Q. My org has an Enterprise Hub subscription and I need to update the number of seats. How can I do this?**
+
+A. The number of seats will automatically be adjusted at the time of the subscription renewal to reflect any increases in the number of members in the organization during the previous period. There’s no need to update the subscribed number of seats during the month or year as it’s a flat fee subscription.
