But I did not receive any reply from ebay customer service.

What should I do from now?

Did ebay ignore me?

You can contact eBay Customer Services advice them the buyer is asking for something totally out of your control.  You have no control over any custome duty a buyer needs to pay.

First you need to log out of this UK site,  and lg into www.ebay.com to continue.

Contact eBay Customer Services this way,  through their help pages.

Lines are open between 5 a.m. and 9 p.m. Pacific Time
