I'm sorry to hear about this situation. It's important to clarify that VAPI does not share or sell any client information. The incident you described seems to be coincidental or possibly due to a security breach or data leak from another source.
To help you identify the cause and resolve the issue, I would recommend the following steps:
1. **Check Your Systems**: Ensure that your systems are secure and that there has been no unauthorized access that could have led to the sharing of client information.
2. **Review API Logs**: Check the logs of your API calls to see if there was any unusual activity or if any third-party services were inadvertently called that could have led to this issue.
3. **Contact Gi-Group Holding**: Reach out to Gi-Group Holding to inquire about how they obtained the client's contact information. It's possible they may have acquired it through other means.
4. **Inform Your Client**: Assure your client that you take data privacy seriously and that you are investigating the matter. Transparency is key to maintaining trust.
5. **Data Privacy Compliance**: Review your data privacy policies and compliance with regulations like GDPR or CCPA to ensure you are following best practices.
6. **Legal Advice**: If necessary, seek legal advice to understand any implications and to ensure you are taking the correct actions.
If you need further assistance with checking the API logs or ensuring your systems are secure, please let me know, and I can guide you through the necessary steps or direct you to the appropriate support channel.
