had ordered an hp 7 voice tab on 7-4-2015 on ebay. And I got the tab on[protected].But today it have suddenly stopped working and showing a blank screen. Ebay people told to contact hp service center. When contacted they said screen damaged.and those people aren't responding properly and telling you ask in ebay itself. And they are also telling that they won't support Ebay sold products. And Ebay people saying that get DOA certificate from hp service centre but thy are not even providing that.Please provide me the DOA certificate so that I get replacement from ebay.
