Another title for this post can be: "Where to find a Yahoo! tech support who knows what he is doing?"
I am writing to this forum because I have totally run out of options. I don't know whom to contact. Yahoo! tech support seems to be filled with people who either don't read what I am writing, or choose to ignore it and just read what they want to read.
I have had this problem for several weeks now. If I try to login to Yahoo! using login.yahoo.com or mail.yahoo.com, I get either of the two error messages: (1) "This id is not yet registered. Are you trying to register for one, etc..", if I use my yahoo.com ID to login. (2) "There was an error, please sign in again with the same ID or a different one", if I use my google.com ID to login.
In the latter case there is an error code of 100 in the URL. No error code is displayed for the first case.
Now here is the funny part. If I use a SOCKS proxy located in another country like Japan, I can login into my Yahoo! account without any problem. So obviously my ID exists and my password has no problem.
I have exchanged atleast 20 mails with Yahoo! support to date on this matter. They insist on making me change my password or resetting my password, and one even suggested me to change my Google password!
I am at my wit's end. Someone, if you know somebody in Yahoo! technical staff who know what they are doing, please direct me to them. This is unbelievable. HELP!!
