Hello qingfeng882009,
Thanks for contacting eBay Customer Service..
We know you need to get your question answered quickly, and in most cases, you'll get a reply from us within 24 to 36 hours. But depending on the question you asked and how many other questions we have to answer right now, it might take up to 72 hours for you to hear back from us.
It will slow things down if you send more than one message about the same issue. We'll answer as soon as we can.
If you need to contact us about anything else, here's how:
1. Click "Help & Contact" at the top of most eBay pages.
2. Enter information about your issue, and then click the "Search" button. Alternately, you can click the "Contact us" button and choose the topic that best matches your question or concern.
3. You'll be given information about your question and the best way to contact us.
We appreciate your patience while we get you the answers you need.
Thanks,
eBay
