Facebook Marketplace can get blocked due to policy violations, suspicious activity, or account restrictions. To unblock it, first, check for any notifications or messages from Facebook explaining the issue. If your access was restricted mistakenly, appeal the decision through the Help Center. Clearing cache, updating the app, or using a different device might also help. If you need further assistance, contacting Facebook support is essential. While Facebook doesn’t have a direct support number, users often search for the https://ebay.pissedconsumer.com/customer-service.html for customer service guidance in similar marketplace issues. Stay compliant with Facebook’s policies to avoid future restrictions.
