How can I resolve the subscription setup error when adding my credit card?

I'm sorry you're having trouble with your account. Unfortunately, I don't have access to account details or the ability to resolve subscription issues directly.

For problems like this, I recommend:

1. Contacting Support via Official Channels:
   Reach out directly to the platform’s support team through the official support page or email. If you've already sent a request, sometimes response times vary. Make sure to include as much detail as possible (error messages, steps taken, and account details) to help them diagnose your issue.

2. Using the Help Forums:
   Although you mentioned not finding an answer there, sometimes a post or a search query in the community forums can help you connect with others who have experienced similar issues. Moderators or experienced users might have additional suggestions or workarounds.

3. Double-Checking Payment Details:
   While it seems unlikely since you've not used any credits yet, verify that your credit card information is entered correctly. Sometimes even small mismatches or glitches can cause unexpected errors.

4. Alternative Communication Methods:
   If the normal support channels aren’t yielding results, look for any alternative contact options (for example, a support phone number or social media channel). Occasionally a public mention of your issue in a managed support community can prompt a faster response.

Since account-related issues often involve sensitive data, handling them through secure, official channels is the best course of action. I hope support gets back to you soon so you can get your account working properly.
