A. 1. Use the 'Follow Up' feature: If you have messaged a seller and haven't received a response, consider sending a polite follow-up message to check in. 2. Check seller's activity: Look at the seller's profile to see if they have been active recently. If they haven't logged in for a while, they may not respond.

B. 3. Explore other listings: If a seller is unresponsive, consider looking for similar items from other sellers. This can help you find what you need without waiting.
