In relation to questions I asked on this thread of the OP it was because they indicated that they did not trust the email sent to them seeking documentation even though they were in contact with ebay about their  account issues. I asked particular questions - to clarify aspects of the OPs posts.

My follow up advice is for anyone who is not confident that ebay correspondence and return email address details are legitimate is to ring ebay yourself and confirm that the details are legitimate with them over phone - the call should take a few minutes.
