When replying to a seller (as a buyer) cannot I not get the "Ebay Rover" to work? Does not work in Chrome, Opera or Firefox is it me or the system? Thanks for your help
rover.ebay.com.au is currently unable to handle this request.HTTP ERROR 500 Had this happen for the last week unable to contact ebay tech support anyone else getting the same?
Is there a site within eBay where members can placed a "wanted" notice for a product that cannot be found by using Bays search engine Any suggestions would be appreciated.
Can someone please tell me what the link is to chat on line with Ebay Staff? Thank you for your help
